Conradi-Hünermann-Happle syndrome

A seven-year-old girl was born with red, scaly skin that later evolved into hypopigmentation and follicular atrophoderma in a widespread distribution that followed Blaschko lines. She also had patchy, scarring alopecia, left microphthalmia, bilateral cataracts, dysmorphic facies, short stature, hip dysplasia, and vertebral abnormalities. An elevated plasma 8(9)-cholestenol level confirmed the diagnosis of Conradi-Hünermann-Happle syndrome, which is caused by mutations in the emopamil binding protein (EBP) gene. This reports highlights the evolution of clinical findings over time in this X-linked dominant form of chondrodysplasia punctata.
