PDE6B (P35913) variants and mutations

PDE6B (also known as P35913) is a human protein-coding gene encoding a rod cGMP-specific 3',5'-cyclic phosphodiesterase subunit beta protein. It hydrolyzes cyclic GMP after light activation in rod photoreceptors, causing cyclic-nucleotide-gated channels to close and initiating the electrical visual response. Biallelic loss-of-function variants cause retinitis pigmentosa, while certain variants can cause congenital stationary night blindness. This analysis covers 1,603 PDE6B variants and mutations. Of these, 81% have computational variant effect predictions. Disease context includes retinitis pigmentosa, congenital stationary night blindness, and Retinal dystrophy. Example PDE6B variants include M1I, M1V, and S2I.
