CRB1 (Protein crumbs homolog 1) variants and mutations

CRB1 (also known as Protein crumbs homolog 1) is a human protein-coding gene encoding a protein crumbs homolog 1 protein. It helps maintain apical polarity and structural organization of photoreceptors and Muller glia in the retina. Biallelic pathogenic variants cause inherited retinal dystrophies including Leber congenital amaurosis and retinitis pigmentosa. This analysis covers 2,551 CRB1 variants and mutations. Of these, 83% have computational variant effect predictions. Disease context includes Leber congenital amaurosis 8, retinitis pigmentosa 12, and Leber congenital amaurosis. Example CRB1 variants include M1?, A2T, and A2E.
