Delineation of the male phenotype in carniofrontonasal syndrome.


We are reporting on a 4-generation family in which 6 individuals had frontonasal dysplasia with variable extracranial abnormalities. All affected persons had hypertelorism, bifid or broad nose, and highly arched palate. Associated abnormalities included cleft lip and palate (1/6), webbed neck (2/6), Sprengel anomaly (2/6), pseudoarthrosis of the clavicle (2/6), pectus excavatum (3/6), narrow, sloping shoulders (3/6), diaphragmatic hernia (2/6), broad first toe (4/6), brachydactyly (3/6), fifth finger clinodactyly (5/6), longitudinal grooves of nails (5/6), shawl scrotum (2/3 males), first degree hypospadias (1/3), and mild mental retardation (1/6). Only one affected female had brachycephaly and right coronal synostosis. Four other affected relatives had varying degrees of facial asymmetry, but normal skull contour. No male to male transmission is observed, and both daughters of an affected male were affected. Based on the phenotype of the 3 affected females, craniofrontonasal syndrome (CFNS) is the likely diagnosis. However, there are 3 affected males in this kindred, and 2 of the 3 had significant anomalies. Affected males also had genital abnormalities and pectus deformity of the chest, not previously reported in this condition. Two of the 3 males have posterolateral diaphragmatic hernia. This family expands the phenotype of affected males.
