Abstract
A girl presented with a phenotype including neonatal hypotonia, psychomotor retardation, mental retardation, short stature, and facial dysmorphism. She demonstrated common features of both 14q31βqter duplication and terminal 14q deletion. She had undergone surgery for patent ductus arteriosus and pyloric stenosis in infancy. Her karyotype was 46,XX,der(14) dup(14)(q32.3 q31.3)del(14)(q32.3). Molecular cytogenetic analysis showed a paternally derived 14q31.3βq32.3 duplication and a terminal 14q deletion and led to the correlations between a particular genotype and phenotype. This is the first description of a deletion and inverted duplication of 14q, and adds 14q to the growing list of the inverted duplication associated with a terminal deletion. Β© 2005 WileyβLiss, Inc.

## Abstract We report a family of anophthalmia with ocular and extraocular manifestations. The proband, his three sisters, and two sons had anophthalmia and preaxial polydactyly in the right hand. Cytogenetic analysis was done for the proband and two of his sons, one of whom was affected. Another m
