Autosomal inheritance of "senile" retinitis pigmentosa. A report of a family with consanguinity

Abstract

We describe two sisters affected with retinitis pigmentosa of late onset. Night blindness and progressive visual field loss occurred after 50 years of age in both cases. The parents of affected individuals were first cousins and there was no known history of other similar cases in previous generations. Autosomal recessive inheritance is suggested for such senile retinitis pigmentosa.
