A gene for a severe lethal form of X-linked arthrogryposis (X-linked infantile spinal muscular atrophy) maps to human chromosome Xp11.3-q11.2.

X-linked arthrogryposis Type I (X-linked infantile spinal muscular atrophy) is a rare disorder showing hypotonia, areflexia, and multiple congenital contractures (arthrogryposis) associated with loss of anterior horn cells and death in infancy. We have studied an X-linked arthrogryposis family using highly polymorphic microsatellite markers throughout the X chromosome. Meiotic breakpoint analysis (concordance analysis) based on shared regions of the founder X chromosome was successful in localizing the X-linked arthrogryposis gene to Xp11.3-q11.2. In this region, the highest two-point lod score was found with DXS991 (Zmax = 2.63, theta = 0.00). In multipoint linkage analysis covering the entire X chromosome, only the region defined by MAOB and DXS991 showed positive lod scores and all other regions showed negative lod scores. These data establish the first gene mapping assignment of an X-linked lethal form of human lower motor neuron disease.

Congenital vertical talus in arthrogryposis and other contractural syndromes.

No practical classification system exists to identify which patients may have successful outcome following treatment of congenital vertical talus in arthrogryposis. We classified 229 patients into five distinct groups: Group I had amyoplasia or so-called classic arthrogryposis, Group II had distal arthrogryposis, Group III had a specific syndrome as a diagnosis, Group IV had severe systemic or neurologic involvement, and Group V had unclassifiable contracture syndromes. No patient with amyoplasia (Group I) had congenital vertical talus. The congenital vertical talus seen in distal arthrogryposis (Group II) was milder than that seen in Groups III or IV and feet in this group responded well to early one-stage surgical correction. Congenital vertical talus that occurred in association with a generalized syndrome or with extensive systemic and neurologic involvement (Groups III and IV) was severe and refractory to treatment. Most children in these groups were unable to walk; therefore, the goal of treatment should be to achieve a pain-free foot to allow fitting of normal shoes. Most children in Group V were able to walk and responded well to operative correction; they should be treated before walking age.

Prenatal diagnosis of arthrogryposis multiplex congenita with increased nuchal translucency but without any underlying fetal neurogenic or myogenic pathology.

Arthrogryposis multiplex congenita is a general term for congenital multiple joint contractures, the aetiology of which is variable. Prenatal diagnosis is usually based on the detection of diminished fetal movements and joint contractures on ultrasound. There are also reports of early diagnosis of arthrogryposis in the first and early second trimester by detection of subcutaneous oedema. We report another case of arthrogryposis multiplex congenita with increased nuchal translucency and scoliosis diagnosed by ultrasonography at 15 weeks of gestation. The pregnancy was terminated at the request of the parents. Post-mortem examination revealed that it was not associated with fetal myopathy or neuropathy. Multiple joint contractures with increased nuchal translucency without any underlying fetal neurogenic and myogenic pathology may be a distinct form of arthrogryposis multiplex congenita.

Survival motor neuron (SMN) polymorphism in relation to congenital arthrogryposis in two Piedmont calves (piemontese).

The term arthrogryposis refers to a symptom complex that is characterised by congenital limb contractures. Arthrogryposis has been reported in man, in farm animals and in pets. Several forms have been reported to have a genetic origin in man. In Brown Swiss and Holstein Friesian cattle, congenital contractures have been recorded and classified as spinal muscular atrophy (SMA). The survival motor neuron gene (SMN) has been suggested as a candidate gene for SMA. In the last 20 years, the National Association of Piedmont Cattle have recorded arthrogryposis cases. We cloned and sequenced SMN cDNA extracted from the spinal cord samples of two animals: one Piedmont calf showing a severe clinical form of arthrogryposis and one normal Piedmont calf. In the affected calf, more than 50% of the 5' end clones showed a ATG > TTG single nucleotide polymorphism (SNP) in exon 1 that should determine a Met > Leu aminoacid change (single point mutation M3L). This mutation is associated with a 9 bp increase length of 5' UTR and to a TTC-->TTT silent mutation in exon 1. No single point mutation or 5' end polymorphism was shown in healthy animals and in the remaining 50% of the clones from the affected calf. We hypothesise a possible pathogenic effect of the 5' end-exon 1 polymorphism.

Comparison of plasma disposition of alkaloids after lupine challenge in cattle that had given birth to calves with lupine-induced arthrogryposis or clinically normal calves.

OBJECTIVE: To compare plasma disposition of alkaloids after lupine challenge in cattle that had given birth to calves with lupine-induced arthrogryposis and cattle that had given birth to clinically normal calves and determine whether the difference in outcome was associated with differences in plasma disposition of anagyrine. ANIMALS: 6 cows that had given birth to calves with arthrogryposis and 6 cows that had given birth to clinically normal calves after being similarly exposed to lupine during pregnancy. PROCEDURES: Dried lupine (2 g/kg) was administered via gavage. Blood samples were collected before and at various time points for 48 hours after lupine administration. Anagyrine, 5,6-dehydrolupanine, and lupanine concentrations in plasma were measured by use of gas chromatography. Plasma alkaloid concentration versus time curves were generated for each alkaloid, and pharmacokinetic parameters were determined for each cow. RESULTS: No significant differences in area under the plasma concentration versus time curve, maximum plasma concentration, time to reach maximum plasma concentration, and mean residence time for the 3 alkaloids were found between groups. CONCLUSIONS AND CLINICAL RELEVANCE: Because no differences were found in plasma disposition of anagyrine following lupine challenge between cattle that had given birth to calves with arthrogryposis and those that had not, our findings do not support the hypothesis that between-cow differences in plasma disposition of anagyrine account for within-herd differences in risk for lupine-induced arthrogryposis.

[2 cases of arthrogryposis].

The authors report two cases of arthrogryposis in two children of 7 1/2 and 13 years; the diagnostic criteria were those of Fisher, combining the joint limitations present since birth in at least two different regions, the absence of progressive neurological involvement, and evident amyotrophy. The different etiopathogenic theories are then discussed: review of the literature concerning cases of myopathic arthrogryposis is not very useful; the twelve cases mentioned in the literature are not homogenous, the histopathological findings were very variable, and the histoenzymological studies have been insufficient. The combination of neurological anomalies with arthrogryposis is undeniable (cerebral atrophy, depopulation of the anterior cornu, anterior radicular changes). They are not always present, however, and are insufficient to explain the symptoms. Consideration should be given to the question of whether the importance of the changes in the connective tissue are not underestimated: the proliferation of the connective tissue is, in fact, most of the time, the essential feature to be seen in a histological section. In connection with this "connective theory" it is important to recall the work of Ionasescu et al. (1970) who demonstrated in vitro the excessive synthesis of connective proteins in the muscles of patients with arthrogryposis.

Extending the spectrum of distal arthrogryposis.

We describe a mother and son with multiple, non-progressive, congenital contractures, camptodactyly and absent flexion creases, expressionless face, blepharophimosis, microstomia, and short stature. Although these cases share similarities with the autosomal-recessive Schwartz-Jampel and Marden-Walker syndromes, they have a different mode of inheritance and lack myotonia, one of the most characteristic findings of the Schwartz-Jampel syndrome. Our cases most closely resemble those previously reported as distal arthrogryposis type IIb, although in our patients the proximal joints are severely affected and extraocular involvement is absent. Hearing loss is present in one and cleft palate in the other of our patients; these findings were previously described in arthrogryposis syndromes other than type IIb. We suggest extending the spectrum of distal arthrogryposis to include these manifestations, since there appears to be significantly overlap between the different syndromes.

Non-lethal arthrogryposis multiplex congenita presenting with cystic hygroma at 13 weeks gestational age.

Arthrogryposis is defined as multiple joint contractures, the aetiology of which is variable. Prenatal diagnosis has focused on diminshed fetal movement and detection of joint contractures on ultrasound. These findings usually do not become evident until 16 to 18 weeks of gestation. Although others (Baty, 1989; Hyett et al., 1997) have reported the diagnosis of arthrogryposis in the first and early second trimester by the presence of nuchal oedema, these reports have all focused on lethal conditions. We report on two female siblings with non-lethal arthrogryposis multiplex congenita. The diagnosis was suspected in the second pregnancy at 13.5 weeks when a large cystic hygroma was detected on ultrasound. Multiple joint contractures became evident at 18 weeks. We hypothesize that the aetiology may be secondary to delay in lymphatic maturation with development of a large cystic hygroma resulting in restriction of fetal movement during early joint formation. Further, the fact that the two female siblings had a similar pattern of facial and joint development, and that their parents are second cousins, suggests an autosomal recessive basis for this form of AMC.

Distal arthrogryposis type II: a family with varying congenital abnormalities.

Five family members with distal arthrogryposis in two generations are reported. Cleft lip and palate, micrognathia, ptosis, webbed neck, kyphoscoliosis, and short stature are seen in one or more affected family members. All individuals with distal arthrogryposis also have trismus. This family does not fit any of the recently proposed five subcategories of type II distal arthrogryposis, nor does it fit any other recognized autosomal dominant condition with distal contractures.

Distal arthrogryposis type IIB: further clinical delineation and 54-year follow-up of an index case.

Distal arthrogryposis IIB is characterized by contractures of the distal joints (especially of the fingers and toes) and ptosis. We recently encountered a father and son with these manifestations. The father was reported 54 years ago as a case of amyoplasia congenita (arthrogryposis multiplex congenita). Both father and son have distal joint contractures, most severe in the hands and feet, as well as ptosis and ophthalmoplegia. In addition, these patients have an unusual distribution of hair loss, and conical teeth. Whether these latter findings are related to the type of distal arthrogryposis present in this family is not known. In spite of their physical limitations both father and son have maintained an active life-style.

Mitochondrial mutation in a child with distal arthrogryposis.

A 15-year-old girl presented with stroke and was found to have a mitochondrial mutation MELAS T3271C. As an infant, she had required casting and surgery for clubbed feet as well as physical therapy for camptodactyly and adducted thumbs. Despite some residual deformities, psychomotor development was normal, but she was extremely small for her age with height, weight, and head circumference below the third centile. A younger brother had similar distal arthrogryposis, but normal height and weight and no history of stroke though he had been diagnosed with attention deficit. The parents and another brother were clinically normal. While the observation of MELAS in a child with distal arthrogryposis could be co-incidental, it raises concern about the possible role of mitochondrial myopathy or neuropathy in causation of distal arthrogryposis.

Hypoechogenicity of fetal long bones: a new ultrasound marker for arthrogryposis.

OBJECTIVE: To demonstrate osteopenia associated with arthrogryposis. METHODS & RESULTS: We describe 3 cases of fetal arthrogryposis seen prenatally with the sonographic feature of severe hypoechogenicity of the long bones. This manifestation of presumed osteopenia is thought to represent osteoporosis secondary with absent fetal movement. CONCLUSION: We describe hypoechogenicity of the fetal bones as a new sonographic feature of arthrogryposis.

Arthrogryposis, renal dysfunction and cholestasis syndrome: report of five patients from three Italian families.

We report on five patients from three families with neurogenic arthrogryposis, cholestasis and tubular renal dysfunction. Despite a similar clinical picture the liver histology showed a broad pathological spectrum, ranging from pigment storage to parenchymal giant cell transformation and ductopenia. The findings are compared with those of other cases from the literature in search of a correct nosology of the syndrome characterized by arthrogryposis, renal and liver disease. CONCLUSION. We propose to consider the picture of arthrogryposis, renal tubular dysfunction and cholestasis as a single syndrome.

VPS33B mutation with ichthyosis, cholestasis, and renal dysfunction but without arthrogryposis: incomplete ARC syndrome phenotype.

Arthrogryposis-renal dysfunction-cholestasis (ARC) syndrome is a rare multisystem disorder first described in 1979 and recently ascribed to mutation in VPS33B, whose product acts in intracellular trafficking. Arthrogryposis, spillage of various substances in the urine, and conjugated hyperbilirubinemia define an ARC core phenotype, in some patients associated with ichthyosis, central nervous system malformation, deafness, and platelet abnormalities. We describe a patient with cholestasis, aminoaciduria, ichthyosis, partial callosal agenesis, and sensorineural deafness who, although homozygous for the novel VPS33B mutation 971delA/K324fs, predicted to abolish VPS33B function, did not exhibit arthrogryposis. The phenotypes associated with VPS33B mutation may include incomplete ARC.

Severe lethal spinal muscular atrophy variant with arthrogryposis.

Spinal muscular atrophies are a clinically and genetically heterogeneous group of disorders. Atypical forms of the disease have also been described, including those with associated sensory deficits, hearing loss, cerebellar hypoplasia, congenital heart defects, arthrogryposis, and bone fractures at birth. The patient described here is a male infant, born to a 30-year-old mother at 34 weeks of gestation complicated with polyhydramnios. The first son of consanguineous parents had died with the same clinical features. The patient required ventilatory support because of respiratory failure after the birth and died on day 13. His physical examination revealed profound generalized hypotonia, absence of deep tendon and neonatal reflexes, dysmorphic facies, arthrogryposis, clinodactyly, and left femur fracture. A muscle biopsy revealed variation in fiber size with occasional hypertrophic fibers. The postmortem examination revealed loss and degeneration of anterior horn cells. We propose that the patient, who presented with severe hypotonia, femur fracture, arthrogryposis, dysmorphic features, history of early death of his brother with the same clinical features and parental consanguinity, had probable X-linked spinal muscular atrophy. However, autosomal-recessive inheritance can not be completely excluded.

Surgical treatment of arthrogryposis of the elbow.

The purpose of this study was to analyze our results of surgical treatment of arthrogryposis of the elbow and to compare our tendon transfer results using range of motion (ROM) criteria versus functional use criteria. Eighteen tendon transfers for elbow flexion in 14 children with arthrogryposis with an average follow-up period of 4 years (range, 1-14 years) and 6 elbow capsulotomies with triceps lengthening in 6 children with arthrogryposis with an average follow-up period of 5 years (range, 2-9 years) were evaluated. Each child was assessed by a questionnaire regarding functional use of the upper extremity, physical examination of ROM and strength, and a videotaped activities of daily living evaluation. Tendon transfer results were classified and compared using 2 methods of evaluation: postoperative strength and ROM and effective functional use of the tendon transfer to perform activities of daily living. The 6 elbow capsulotomies improved from an average preoperative arc of 17 degrees of motion (average extension, -2 degrees; average flexion, 19 degrees) to an average final follow-up arc of 67 degrees (average extension, -25 degrees; average flexion, 92 degrees). The 18 tendon transfers evaluated by strength and ROM criteria showed 9 triceps to biceps transfers in 9 arms (7 good, 1 fair, and 1 poor), 5 pectoralis to biceps transfers in 4 arms (1 good, 3 fair, and 1 poor), and 4 latissimus dorsi to biceps transfers in 3 arms (2 good and 2 fair). Evaluation by functional use criteria gave the same result in 13 transfers and downgraded the result in 5; the downgraded results were due to resultant flexion contracture or limited functional use because the transfer was in the nondominant arm. Based on this review, optimal surgical candidates for tendon transfer are children older than 4 years, who have full passive ROM of the elbow in the dominant arm, and at least grade 4 strength of the muscle to be transferred.

Arthrogryposis multiplex congenita.

The common factor causing congenital arthrogryposis is lack of fetal movements. This can result from a large number of disorders. They may be neuropathic, affecting the brain, the spinal cord, or the peripheral nerves; they may be abnormalities of the muscles, such as myasthenia gravis, congenital muscular dystrophies or mitochondrial cytopathies; they may be diseases of the connective tissues; or they may be conditions which limit the space within the uterus; or they may result from defects of the uterine environment. These are discussed in turn. Typical clinical findings are given and it is emphasised that the arthrogryposis is often a manifestation of certain syndromes, some the result of abnormal chromosomes. Although it is not within the scope of this review article to describe these in detail, examples are given. In particular the subgroup of distal arthrogryposes and amyoplasia are considered. The importance of trying to define a cause is especially the need to give reliable genetic advice to the parents and also to establish a prognosis. The diagnosis will often be made by the associated symptoms and signs, and sometimes by tests such as electromyography and muscle biopsy. Although some of the diseases will be fatal early in life, there are many instances when the child will survive into adult life; if due attention is given to the treatment, particularly orthopedic procedures, and to social and educational management. This can only be done realistically if there is a good idea of the natural history of the condition underlying the arthrogryposis.

Asymmetric arthrogryposis multiplex congenita with focal pachygyria.

A male infant with predominantly right-sided arthrogryposis multiplex congenita is presented. His posture in the lower extremities was asymmetric, and left thoracic scoliosis was present. This patient also manifested focal pachygyria dominantly affecting the contralateral cerebral hemisphere and hypoplasia of the corpus callosum, brainstem, and cerebellar vermis. Generalized tonic seizures began at 2 months of age, and an electroencephalogram revealed epileptic discharge. Biopsy of the right biceps revealed a nonspecific change. A direct causal relationship between neuronal migration disorders and arthrogryposis multiplex congenita has not been established, but considering the abnormal neuronal migration along the entire neural axis in focal pachygyria, the predominantly right-sided arthrogryposis in this patient was speculated to be closely related to the pachygyria of the frontal and temporal lobes dominantly affected in the left cerebral hemisphere.
