This genetic disorder affects ectoderm derivatives, upper and lower extremities, and retina. The clinical features include hypotrichosis with sparse and short hair on the scalp, sparse and short eyebrows and eyelashes, and partial anodontia. The hands are often more severely affected than the feet. The anomalies vary from the absence of digits to polydactyly, syndactyly, and camptodactyly. The retinal lesion appears as a central geographic atrophy of the retinal pigment epithelium and choriocapillary layer of the macular area with coarse hyperpigmentation and sparing of the larger choroidal vessels.
