Mutation screen of the TUB gene in patients with retinitis pigmentosa and Leber congenital amaurosis.

ABSTRACT: TUB is the first identified member of the TULP family of four proteins with unknown function. A spontaneous mutation in murine tub causes retinal degeneration, obesity, and deafness. Mutations in another member of the TULP family, TULP1, are a cause of autosomal recessive retinitis pigmentosa (RP). These findings prompted us to investigate TUB as a candidate gene for RP and Leber congenital amaurosis (LCA). A mutation screen of the entire coding region of the TUB gene in 159 unrelated patients with autosomal recessive RP, 114 unrelated patients with simplex RP, and 21 unrelated patients with LCA uncovered 18 sequence variations. Of these, seven were missense mutations, six were isocoding changes, and five were intronic polymorphisms. All seven missense mutations were identified as heterozy
