Anophthalmia in a retarded girl with partial trisomy 4p and 22 following a maternal translocation, rcp(4;22)(p15.2;q11.2).

An 18-year-old girl displayed left anophthalmia and right severe microphthalmia, mild dysmorphic features of facies and distal limbs, a right preauricular pit, and moderate mental retardation. She was trisomic for the distal part of the short arm of chromosome 4 and the proximal segment of chromosome 22, due to unbalanced 3:1 segregation of a maternal 4;22-translocation. Anophthalmia is a rare finding in chromosome aberrations in general, and particularly in patients not featuring other severe malformations and severe to profound mental retardation.
