✦ Synopsis
CHILD syndrome (congenital hemidysplasia with ichthyosiform nevus and limb defects) occurs, as a rule, exclusively in girls because the underlying X-linked gene exerts a lethal effect on male embryos. In this report the characteristic manifestations of CHILD syndrome are described in a 2-yearold boy with a normal chromosome constitution 46,XY. This exceptional case is best explained by the assumption of an early somatic mutation and thus compatible with the concept of X-linked dominant malelethal inheritance of this trait.
