Oculotrichodysplasia (OTD): a new probably autosomal recessive condition.

A brother and sister, the offspring of first cousins, are described with retinitis pigmentosa, trichodysplasia (hypotrichosis and structural changes), dental anomalies, and onychodysplasia. This is a pure ectodermal dysplasia of the tricho-odonto-onychial subgroup, probably due to an autosomal recessive gene.
