Incontinentia pigmenti (type 1) and X;5 translocation
Abstract
The authors present a 5-year-old girl with total absence of speech, dysmorphic features, pigmented lesions on the legs, an abnormal EEG and otherwise normal intelligence representing a mild form of type 1 Incontinentia pigmenti associated with an (X;5) (p11.2;q35.2) apparently balanced translocation prenatally diagnosed. The seven previous translocation type 1 IP patients are reviewed and all have the same Xp11 breakpoint. Somatic cell hybrids have been made to further study this breakpoint and further define the putative type 1 IP gene.
