Mild growth retardation and developmental delay, microcephaly, and a distinctive facial appearance.

We describe a brother and sister from one family and a girl from a second, unrelated family; they have a syndrome of pre- and post-natal growth deficiency, developmental delay, a friendly personality, microcephaly, and a distinctive facial appearance marked by thick eyebrows, full cheeks, and a short nose with the columella inserted below the nasal alae. We think this is a new syndrome probably inherited as an autosomal recessive trait.

New dominant syndrome of pterygium colli, mental retardation, and digital anomalies.

We describe a proband and his mother who appear to have a new dominant syndrome of mental retardation: pterygium colli, unusual features, and digital anomalies. The craniofacial abnormalities include brachycephaly, epicanthus inversus, angulated eyebrows, upward slanting of the palpebral fissures, ptosis, hypertelorism, and prominent low set, posteriorly rotated ears. The digits are remarkable for proximally displaced small thumbs, widened interphalangeal joints, and broad terminal phalanges.

"New" ectodermal dysplasia with mental retardation and syndactyly.

We describe a girl with an unusual form of ectodermal dysplasia. She was mildly mentally retarded, had normal height, weight, and head circumference, a large scalp defect, a peculiar face with large palpebral fissures, a broad nasal bridge and constantly open mouth, abnormally-modeled ears, syndactyly of fingers/toes, mild hypohidrosis, and severe onychogryposis. Her hair was short, abundant, and stiff, her eyebrows were sparse, and her skin was dry. Analysis of the literature showed that this type of association of ectodermal dysplasia and other defects has not been previously described.

Segregation of a t(1;3) translocation in multiple affected family members with both types of adjacent-1 segregants.

A subtle balanced translocation involving the terminal regions of 1q and 3p was identified in a large family by high-resolution karyotype analysis and confirmed by fluorescence in situ hybridization (FISH) analysis. In this family, segregation of a balanced t(1:3)(q42.3;p25) chromosome translocation led to two types of viable unbalanced complements. The proband inherited the derivative chromosome 3, resulting in partial trisomy of 1q and partial monosomy of 3p. A paternal uncle and cousin had the reciprocal rearrangement with a derivative of chromosome 1, resulting in partial monosomy for 1q and partial trisomy for 3p. While profound mental and physical retardation and congenital heart defects were characteristics for both rearrangements, facial dysmorphism was quite distinct for each imbalance. Individuals who had the derivative chromosome 3 had a long face, wide eyebrows, small palpebral fissures, hypertelorism, prominent glabella, a large tip of the nose, long philtrum with thin upper lip, and low set-ears. In contrast, family members with the derivative of chromosome 1 had a tall forehead with bifrontal narrowing, full and large cheeks, and large simple ears. Since the translocated segments are small and approximately equal in size in this family, it is not surprising that viability was seen in individuals with both types of adjacent-1 segregation. In this kindred, the ratio of normal to abnormal individuals born to balanced carriers is believed to be about 1:1.5. This suggests that the recurrence risk for carriers is 50%.

A diagnostic conundrum: two siblings with features overlapping the Kabuki and Malpuech syndromes. A new MCA syndrome?

We report two siblings, a boy and a girl, with a constellation of anomalies that overlap the phenotypes of Kabuki and Malpuech syndromes. Both patients had a facial appearance suggestive of Kabuki syndrome, sagittal vertebral clefts, and short fifth fingers. In addition, the girl had brachydactyly of the index finger, and the boy, cleft lip and palate, mild postnatal growth deficiency, coarctation of the aorta, ventricular septal defect, patent ductus arteriosus, and a caudal appendage. The fact that this pattern of anomaly occurred in siblings, together with the presence of sparse eyebrows medially, rather than laterally, in both patients and a caudal appendage in the boy, militates against the diagnosis of Kabuki syndrome. Furthermore, the presence of a caudal appendage in a child with cleft lip and cleft palate and renal abnormalities is suggestive of Malpuech syndrome. The normal growth pattern and psychomotor development observed in both children, however, is inconsistent with this diagnosis, although they may represent a milder end of the phenotypic spectrum for Malpuech syndrome. Alternatively, we conclude that the condition may represent a distinct multiple congenital anomaly (MCA) syndrome. The occurrence of a pattern of MCA in two siblings with phenotypically normal parents and normal cytogenetic studies, including high-resolution banding and subtelomeric probes, points toward an autosomal recessive mode of inheritance. However, germinal mosaicism and other types of non-traditional inheritance, such as a defect in genomic imprinting or uniparental disomy, should also be considered.

9q34.3 deletion syndrome in three unrelated children.

We described three unrelated children with cryptic 9q34.3 rearrangements and similar clinical manifestations: two with 9q34.3 terminal deletions and the other with an unbalanced translocation involving 9q34.3-qter monosomy and 6p25-pter trisomy. Common features among the three we studied and the other six patients with 9q34.3 deletions in the literature include microcephaly, mental retardation (MR), hypotonic, and epileptic seizures. Their facial characteristics included flat face, arched eyebrows, synophrys, hypertelorism, short nose, anteverted nostrils, carp mouth, protruding tongue, micrognathia, and pointed chin. Other frequent abnormalities were cardiac abnormalities, cryptorchidism or hypospadias, and abnormal toes. These findings are characteristic enough to be a clinically recognizable syndrome.

Ablepharon-macrostomia syndrome in a 46-year-old woman.

Ablepharon-macrostomia syndrome (AMS) is a rare condition reported to date in 13 patients worldwide. AMS is characterized by absent or short eyelids, absent eyebrows and eyelashes, macrostomia, and external ear abnormalities. Additional features include alopecia or sparse hair, hypoplastic malar region, redundant skin, rudimentary nipples, abnormal genitalia. While the AMS phenotype is well delineated in infants and children, clinical manifestations are rather poorly characterized in adulthood. Here, we report on an Italian woman who received a diagnosis of AMS at the age of 46 years after several surgical treatments. A clinical comparison between our patient and previously reported AMS cases aids in delineating the adult phenotype of AMS and further broadens the clinical spectrum of this condition.

A novel missense mutation in the galactosyltransferase-I (B4GALT7) gene in a family exhibiting facioskeletal anomalies and Ehlers-Danlos syndrome resembling the progeroid type.

The Ehlers-Danlos syndrome (EDS) is a heterogeneous group of heritable connective tissue disorders characterized by skin hyperextensibility, joint hypermobility, and tissue fragility. Several genes have been implicated to result in EDS phenotypes. The progeroid type of EDS is characterized by wrinkled, loose skin on the face, curly fine hair, scanty eyebrows and eyelashes, in addition to the classical features of EDS. Here we describe two similarly affected individuals in two sibships of a large consanguineous family from Qatar. DNA samples from affected and unaffected members of the family were analyzed for homozygosity of polymorphic markers associated with genes that have been implicated in EDS. Among 28 markers analyzed, homozygosity was only observed for D5S469 and D5S2111, which were markers for galactosyltransferase-I (B4GALT7) located on chromosome 5q35.2, where the previously reported progeroid-like variant of EDS has been mapped. Exons harboring the coding regions and exon-intron junctions of B4GALT7 were amplified by PCR and examined for mutations. A homozygous misssense C to T substitution at nucleotide 808 in the coding region was discovered in both affected individuals. The carrier parents were heterozygous for this mutation, which was not found among 76 DNA samples from control individuals of the same ethnicity. Segregation of this novel mutation in the family further confirmed the allelic variant and its recessive mode of inheritance in this type of EDS. The C to T substitution results in an arginine to cysteine change at amino acid residue 270 that is located in the catalytically active extracellular C-terminal domain. This change could result in abnormal protein folding and/or aberrant interactions of mutated galactosyltransferase-I with other extracellular matrix proteins leading to the development of a progeroid-like phenotype in affected individuals.

Another case of interstitial del(12) involving the proposed cardio-facio-cutaneous candidate region.

Recent reports of patients with interstitial deletions involving the long arm of chromosome 12 have led to the proposal of a candidate region for the cardio-facio-cutaneous syndrome (CFCS) at (12)(q21.2q22). We now report a patient with an interstitial deletion, del(12)(q21.1q21.3) that overlaps the proposed critical region. The patient is an 11-year-old female with developmental delay. Her growth was normal but she is microcephalic with low set ears. In common with other patients with deletions in this region, she had fine, sparse head and eyebrow hair and a hyperkeratotic follicular rash, which involved her face and limbs. She does not have the diagnostic features of the CFC syndrome.

Cardiofaciocutaneous syndrome (CFC) with congenital peripheral neuropathy and nonorganic malnutrition: an autopsy study.

Many phenotypic manifestations have been reported in cardiofaciocutaneous (CFC) syndrome, but none, to date, are pathognomonic or obligatory. Previous histopathological studies reported findings in skin and hair; no autopsy studies have been published. We report the clinical and autopsy findings of a 7-year-old boy with severe CFC syndrome and malnutrition of psychosocial origin. Manifestations of CFC, reported previously, included macrocephaly and macrosomia at birth; short stature; hypotonia; global developmental delays; dry, sparse thin curly hair; sparse eyebrows and eyelashes; dilated cerebral ventricles; high cranial vault; bitemporal constriction; supraorbital ridge hypoplasia; hypertelorism; ptosis; exophthalmos; depressed nasal bridge; anteverted nostrils; low-set, posteriorly-rotated, large, thick ears; decayed, dysplastic teeth; strabismus; hyperelastic skin; wrinkled palms; keratosis pilaris atrophicans faciei; ulerythema ophryogenes; hyperkeratosis; gastroesophageal reflux; and tracheobronchomalacia. Additional findings, not previously reported, include islet cell hyperplasia, lymphoid depletion, thymic atrophy and congenital hypertrophy of peripheral nerves with onion bulb formations. Although the islet cell hyperplasia, lymphoid depletion, and thymic atrophy are nonspecific findings that may be associated with either CFC or malnutrition, the onion bulb hypertrophy is specific for a demyelinating-remyelinating neuropathy. These findings implicate congenital peripheral neuropathy in the pathogenesis of the developmental delays, feeding difficulties, respiratory difficulties, ptosis and short stature in this case. Additional studies of other cases of CFC are needed.

Facial and physical features of Aicardi syndrome: infants to teenagers.

Aicardi syndrome is a sporadic disorder that affects primarily females and is hypothesized to be caused by heterozygous mutations in an X-linked gene. Its main features include of a triad of infantile spasms, agenesis of the corpus callosum, and distinctive chorioretinal lacunae. Additional common findings include moderate to profound mental retardation, gray matter heterotopia, gyral anomalies, and vertebral and rib defects. To date, no consistent facial dysmorphisms have been described. We examined 40 girls with Aicardi syndrome and determined that consistent facial features appeared in over half the study participants and included a prominent premaxilla, upturned nasal tip, decreased angle of the nasal bridge, and sparse lateral eyebrows. Externally apparent microphthalmia was seen in 10/40 (25%). Various skin lesions (including multiple nevi, skin tags, hemangiomas, one giant melanotic nevus, and a history of a previously removed angiosarcoma) were present in 8/40 (20%). Hand abnormalities were seen in 3/40 (7.5%) and included camptodactyly, proximal placement of the thumb and hypoplasia of the fifth finger. This study clearly delineates the existence of a distinctive facial phenotype of Aicardi syndrome not previously described. We recommend that features of a prominent premaxilla with upturned nasal tip and vascular malformations/vascular tumors be added to the modified diagnostic criteria in order to improve the ability of geneticists to diagnose Aicardi syndrome.

Ehlers-Danlos syndrome type VIB with characteristic facies, decreased curvatures of the spinal column, and joint contractures in two unrelated girls.

Two unrelated girls, aged 11 and 14 years, with clinical manifestations of Ehlers-Danlos syndrome (EDS) type VIB, characteristic facies, skeletal abnormalities, and other features are described. They had Marfanoid habitus with pectus excavatum; fragile, hyperextensible, and readily bruisable skin with widened, atrophic scars; recurrent hematomas; generalized joint laxity; hypotonia; scoliosis; and mild delay of gross motor development. Lysyl hydroxylase deficiency was ruled out in Patient 1. Parental consanguinity was present in Patient 2. They both had, in early childhood, down-slanting palpebral fissures, drooping lower eyelids, short nose, small mouth, and long philtrum. Facial features that persisted included thick eyebrows, hypertelorism, strabismus, blue sclerae, low-set, and slanted ears, hypoplastic columella, high-arched palate, and thin upper lip. They had tubular stenosis of the phalanges, metacarpals, and metatarsals; decreased physiological curvatures of the spinal column with tall vertebrae; and joint contractures including talipes equinovarus and progressive talipes valgus. Their hearing of high-pitched sounds was impaired. They had constipation and recurrent cystitis with an enlarged bladder. In view of these findings, we propose that these two girls represent a clinically recognizable subgroup of EDS type VIB.

Triplication of 8p22-8p23 in a patient with features similar to Kabuki syndrome.

Kabuki syndrome (KS) comprises multiple congenital anomalies and distinctive facial appearance. Although a number of chromosome abnormalities have been described in patients with KS-like phenotypes, no consensus has been reached regarding the genetic basis underlying the classic Kabuki phenotype. A recent study reported on 8p22-8p23.1 duplication in patients diagnosed with KS; however, a number of other studies have not found this duplication in patients with classic KS. We report on a girl with triplication of 8p22-8p23 who has mental retardation and some features suggestive of KS, including growth retardation, left-sided obstructive heart lesion, long-appearing palpebral fissures, hypertelorism, sparse lateral eyebrows, prominent ears, and persistent fetal fingertip pads. She does not have the typical facial gestalt of KS, nor does she have other more specific findings of KS. We propose that abnormal copy number of genes in the 8p22-8p23 region results in a syndrome of multiple congenital anomalies with many features that overlap with classic KS. However, data from this patient and others with similar duplications in the literature suggest that duplication or triplication of 8p22-8p23 represents a recognizable pattern of malformation distinct from classic KS. The exact genetic abnormality underlying KS currently remains unknown.

Familial complex 3q;10q rearrangement unraveled by subtelomeric FISH analysis.

In recent years, subtelomeric rearrangements have been identified as a major cause of multiple congenital anomalies/mental retardation syndromes. Currently, more than 2,500 individuals with mental retardation have been tested and reported in whom subtelomeric rearrangements were detected ranging from 2% to 29%. Therefore, subtelomeric FISH analysis is indicated as a second tier test after high-resolution G-banding analysis in patients with otherwise unexplained developmental delay/mental retardation and/or multiple congenital anomalies. We describe a patient and her three maternal female cousins, all showing an undiagnosed MCA/MR syndrome, associated with the same complex subtelomeric rearrangement. Subtelomeric FISH testing performed between 3(1/2) and 18 years after the initial karyotype showed, in all four patients, distal trisomy 3q and distal monosomy 10q as follows: 46,XX,ish der(10)t(3;10)(q29;q26.3)mat(D10S2488+,D10S2490-, D3S1272+,D10Z1+). Parental subtelomeric FISH analysis showed that the proposita's mother and three of four brothers and one of two sisters had a cryptic balanced 3:10 telomere translocation. The three brothers with the balanced translocation were father to one each of the three proband's cousins. All four affected girls showed a similar phenotype with pre/postnatal growth retardation, microcephaly, severe developmental delay/mental retardation, poor/absent speech, and a distinct pattern of malformation. On examination there were coarsening of facial features with low fronto-temporal hairline; thick eyebrows; bilateral epicanthal folds; hypertelorism; prominent nose with squared nasal root and narrow alar base; low-set posteriorly rotated large ears with a prominent anthelix; high arched palate; prominent chin; hands/feet brachydactyly; bilateral squint; hypotonia; and muscle hypotrophy. A slow overall improvement was seen in all patients over time. To our knowledge, this complex subtelomeric rearrangement in our patients has never been reported so far. Monosomy 10q has recently been described either isolated or as part of a complex rearrangement involving telomeres other than the 3q. Trisomy 3q29 has not yet been reported, but our patients resembled cases with 3q26 trisomy suggesting that the critical region of duplication for this phenotype is in 3q29.

Clinical features and management issues in Mowat-Wilson syndrome.

Mowat-Wilson syndrome (MWS) is a relatively newly described multiple congenital anomaly/mental retardation syndrome. Haploinsufficiency of a gene termed ZFHX1B (also known as SIP1) on chromosome 2 is responsible for this condition, and clinical genetic testing for MWS recently became available. The majority of reports in the literature originate from Northern Europe and Australia. Here we report our clinical experience with 12 patients diagnosed with MWS within a 2-year period of time in the United States, with particular emphasis on clinical characteristics and management strategies. Individuals with this condition have characteristic facial features, including microcephaly, hypertelorism, medially flared and broad eyebrows, prominent columella, pointed chin, and uplifted earlobes, which typically prompt the clinician to consider the diagnosis. Medical issues in our cohort of patients included seizures (75%) with no predeliction for any particular seizure type; agenesis of the corpus callosum (60% of our patients studied); congenital heart defects (75%), particularly involving the pulmonary arteries and/or valves; hypospadias (55% of males); severely impaired or absent speech (100% of individuals over 1 year of age) with relatively spared receptive language; and Hirschsprung disease (50%) or chronic constipation (25%). The incidence of MWS is unknown, but based on the number of patients identified in a short period of time within the US, it is likely greatly under recognized. MWS should be considered in any individual with severely impaired or absent speech, especially in the presence of seizures and anomalies involving the pulmonary arteries (particularly pulmonary artery sling) or pulmonary valves.

Spectrum of dolichospondylic dysplasia: two new patients with distinctive findings.

Dolichospondylic dysplasia (DD) is a rare skeletal dysplasia primarily characterized by tall vertebral bodies and disproportionate short stature. Radiographic manifestations include tall vertebral bodies and gracile bones of the hands. Patients usually have eye and ear findings in addition to borderline mental retardation; however, tall vertebral bodies and slender tubular bones are also seen in the 3-M syndrome. Patients with the 3-M syndrome have a characteristic face with a triangular shape, frontal bossing, a flattened malar region, full eyebrows, a short nose with a bulbous tip, upturned nares, and full lips. We present two unrelated patients who share a distinct phenotype and have tall vertebral bodies, overtubulation of long bones, and short tubular bones of the hands and feet. We discuss the overlapping and distinguishing features between DD and the 3-M syndrome. Patient 1 was a 13-year-old female, and patient 2 was an unrelated adult female. These patients had normocephaly and short stature. They shared a common phenotype consisting of mild malar hypoplasia, a narrowed nasal body with a fleshy tip, full lips, and normal intelligence. In addition, they showed mild hand and foot abnormalities. These two patients lack many of the typical clinical features of both DD and the 3-M syndrome. They share a common phenotype and likely represent a distinct disorder. The spectrum of disorders with tall vertebral bodies as a key feature may include different entities that may be further defined with the characterization of the molecular defect(s).

Magnetic resonance imaging and permanent cosmetics (tattoos): survey of complications and adverse events.

PURPOSE: To use a survey to determine the incidence of complications and adverse events in individuals with permanent cosmetics (e.g., tattooed eyeliner, eyebrows, lips, cheeks, etc.) who underwent magnetic resonance (MR) imaging. MATERIALS AND METHODS: A questionnaire was distributed to clients of cosmetic tattoo technicians. This survey asked study subjects for demographic data, information about their tattoos, and for their experiences during MR imaging procedures. RESULTS: Data obtained from 1032 surveys were tabulated. One hundred thirty-five (13.1%) study subjects underwent MR imaging after having permanent cosmetics applied. Of these, only two individuals (1.5%) experienced problems associated with MR imaging. One subject reported a sensation of "slight tingling" and the other subject reported a sensation of "burning"; both sensations were transient in nature. CONCLUSION: Based on these findings and information in the peer-reviewed literature, it appears that MR imaging may be performed in patients with permanent cosmetics without any serious soft tissue reactions or adverse events. Therefore, the presence of permanent cosmetics should not prevent a patient from undergoing MR imaging.

Multicenter study of noninvasive radiofrequency for periorbital tissue tightening.

BACKGROUND AND OBJECTIVES: This 6-month study evaluated the efficacy and safety of treatment with a nonablative radiofrequency (RF) device. STUDY DESIGN/MATERIALS AND METHODS: Eighty-six subjects received a single treatment with the ThermaCool TC System (Thermage, Inc., Hayward, CA) and were evaluated for 6 months after treatment. RESULTS: Independent scoring of blinded photographs resulted in Fitzpatrick wrinkle score improvements of at least 1 point in 83.2% (99/119) of treated periorbital areas. Treating physicians, without reference to pre-treatment photographs, noted improvements in 28.9% (48/166) of treatment areas. Fifty percent (41/82) of subjects reported being satisfied or very satisfied with periorbital wrinkle reductions. Objective photographic analysis showed that 61.5% (40/65) of eyebrows were lifted by at least 0.5 mm. Rates and duration of edema/erythema were very low (e.g., vs. ablative procedures). Overall 2nd-degree burn incidence was 0.36% (21 per 5,858 RF applications). Three patients had small areas of residual scarring at 6 months. CONCLUSIONS: A single treatment with this RF tissue tightening (RFTT) device produces objective and subjective reductions in periorbital wrinkles, measurable changes in brow position, and acceptable epidermal safety. These changes were indicative of a thermally induced early tissue-tightening effect followed by additional tightening over a time course consistent with a thermal wound healing response.
