Autosomal recessive familial exudative vitreoretinopathy: evidence for genetic heterogeneity

Abstract
Two unrelated families with familial exudative vitreoretinopathy (FEVR) show apparent autosomal recessive inheritance rather than the previously reported autosomal dominant or X‐linked recessive mode of inheritance. Compared with the other modes of inheritance, the inherited clinical features here include earlier onset (at birth) and a more severe progressive course.
