Inherited progressive cone--rod dystrophy and alopecia.

Two young sisters of Yemenite Jewish family with progressive cone-rod dystrophy accompanied with progressive alopecia of the scalp in one patient and with alopecia of the scalp and eyelashes in the other patient are presented. This rare disease seems to be autosomal recessively inherited since the patient's parents are first cousins and the family history is positive for a paternal grandmother and great-aunt having the same condition.
