Genes affected
RPGRIP1 (HGNC:13436): (RPGR interacting protein 1) This gene encodes a photoreceptor protein that interacts with retinitis pigmentosa GTPase regulator protein and is a key component of cone and rod photoreceptor cells. Mutations in this gene lead to autosomal recessive congenital blindness. [provided by RefSeq, Oct 2008]
