X-linked adrenal hypoplasia congenita (AHC) is caused by mutations in the NR0B1 gene. This gene encodes an orphan member of the nuclear receptor superfamily, DAX1. Ongoing efforts in our laboratory have identified nine novel NR0B1 mutations in X-linked AHC patients (Y81X, 343delG, 457delT, 629delG, L295P, 926-927delTG, 1130delA, 1141-1155del15, and E428X). Two additional families segregate previously identified NR0B1 mutations (501delA and R425T). Sequence analysis of the mitochondrial D-loop indicates that the 501delA family is unrelated through matrilineal descent to our previously analyzed 501delA family.
We report on three male patients from a single family with a brachyturricephaly, "pugilistic" facial appearance, a muffled voice, cardiomyopathy, muscular hypertrophy, broad hands, wide feet with progressive pes cavus deformities, dislocation of toes, variable congenital hip dislocation, and scoliosis. Three other males in the family, now deceased from cardiac disease, appear to have had the same disorder. The mother of the propositus has milder signs of the syndrome. All affected males are related through the maternal line. These cases represent an apparently previously undescribed X-linked recessive syndrome.
The authors used the Teller acuity cards to assess the visual acuity of 51 infants and children with Down syndrome aged between two months and 18 years. The success rate and test times were comparable to those reported for normally developing children. Even those subjects in the study who were free of ocular disorders and/or who were wearing optical correction during testing showed significantly poorer visual acuity than individuals without Down syndrome. The development of visual acuity in infants and children with Down syndrome lags behind that of age-matched peers without Down syndrome, especially after the age of six months. These findings are discussed in terms of the neurological and optical factors that might account for the deficits in visual acuity that were observed.
We describe several members of a family with Van der Woude syndrome, a genetic and congenital malformation syndrome with autosomal dominant inheritance and 70% to 80% penetrance with variable expressivity. It is characterized by clinical signs localized to the face, such as bilateral or unilateral pits on conical elevations in babies or extensive depressions in adults, both in the vermilion border of the lower lip, with cleft lip, with or without cleft palate and uvula. Small accessory or heterotopic salivary glands empty into sinuses or fistulas in the lips. This eight member family had various clinical signs of the condition. All had cleft lip and palate. We studied the major characteristics of the eight patients and describe histopathologic and immunohistochemical features.
