The Aase syndrome. Case report and review of the literature.

A 5-month-old boy with congenital hypoplastic anaemia and triphalangeal thumbs, known as the Aase syndrome, is described. In addition he had unilateral cleft lip and palate and abnormal dermatoglyphics. Only ten cases have been reported previously; these are reviewed. This case is the third patient reported to have the Aase syndrome who also has a cleft lip. Bone marrow cultures failed to stimulate production of erythropoietic precursors.

Two cases of interstitial deletion of the long arm of chromosome 1: del(1)(q21----q25) and del(1)(q41----q43).

Two unrelated children, one with a proximal interstitial deletion 1 (1(pter----q21: :q25----qter] and the other one with a distal interstitial deletion 1 (1(pter----q41: :q43----qter] are presented. The clinical features of the patient with a proximal deletion (q21-q25) correspond with those of eight earlier reported cases with a deletion 1q21/22/23----q25. The second patient with the distal interstitial deletion (q41-q43) is the first case published as far as we know. The clinical characteristics of the latter patient are compared with those of six cases with a terminal deletion 1q with at least one common band missing (1q42).

Interstitial deletion of the long arm of chromosome 11.

A girl with an interstitial deletion of the long arm of chromosome 11 is described. The patient was mildly mentally retarded and showed some facial dysmorphic features, including hypertelorism, ptosis, and cleft palate.

Roentgencephalometric measurements in trisomy 8 mosaicism: report of three cases.

Roentgencephalometric anomalies in three cases of Warkany syndrome (trisomy 8 mosaicism) are described. These include asymmetry of the mandible with a wide gonial angle and a high and narrow symphysis; SNA (anteroposterior position of maxilla) and SNB (anteroposterior position of mandible) values indicate a backward position of the mandible. Other findings point to a disturbance in the vertical growth of the facial skeleton. These measurements may explain at least part of the facial phenotype and may aid in diagnosis, especially in those cases with an uncertain clinical diagnosis and "normal" karyotype in peripheral blood lymphocytes.

A new short rib syndrome: report of two cases.

We describe two unrelated malformed infants who died shortly after birth and who had multiple congenital anomalies including hydrops and ascites, facial abnormalities (with median cleft of the upper lip), narrow thorax, protuberant abdomen, and short, bowed limbs. Postmortem radiographs showed very short ribs and disproportionately short long tubular bones; no metaphyseal abnormalities were present. Comparison with earlier described short-rib/short-rib-polydactyly syndromes suggest that the disorder present in our two cases is a new type of short-rib syndrome. One of our patients was born to a consanguineous couple; in a subsequent pregnancy, real-time ultrasonography in the second trimester showed that the female fetus had the same abnormalities as its sib. Diagnosis was confirmed after elective abortion. This suggests that this short-rib syndrome may be an autosomal recessive disorder.

Partial monosomy 10p syndrome.

A 7 year-old girl is described with a de novo deletion of the short arm of chromosome 10 (qter p13:). The clinical features of: mental retardation, a large asymmetric head, antimongoloid slant, exophthalmos, epicanthus, ptosis, abnormal ears, pectus excavatum and widely spaced nipples are compared with those of five earlier reported cases with a deletion 10p. The data available suggest the existence of a clinically recognizable monosomy 10p syndrome.

Partial trisomy 10q: a recognizable syndrome.

Five cases from two nonrelated families with partial trisomy 10q due to a reciprocal translocation t(10;17)(q25;p13) and t(10;11)(q24;q23), respectively, are reported. The phenotypic findings are compared with those of 17 previously published cases; the clinical data justify the conclusion that cases with trisomy 10q show a specific syndrome of mental retardation and malformation characterized by psychomotor retardation, growth retardation, hypotonia, high forehead, flat face, fine and arched eyebrows, antimongoloid slant of the eyes, narrow palpebral fissures, hypertelorism, short nose, bow-shaped mouth, short neck (kypho)scoliosis, and in some cases microcephaly.

Two cases with different deletions of the long arm of chromosome 7.

Two mentally and physically retarded girls, one with an interstitial deletion 7 (pter leads to q21::q32 leads to qter), and the other with an interstitial deletion 7 (pter leads to q11::q22 leads to qter), are described. Their clinical features are compared with those of 11 earlier reported cases with a deletion 7q. The Hageman factor, the locus of which is assigned to the distal part of 7q, was in both cases within normal limits. The data available do not justify the delineation of a specific clinical syndrome.
