CHM (P24386) variants and mutations

CHM (also known as P24386) is a human protein-coding gene encoding a rab proteins geranylgeranyltransferase component A 1 protein. It enables prenylation of Rab GTPases by delivering Rab proteins to geranylgeranyl transferase, supporting membrane trafficking in retinal and other cells. Loss-of-function variants cause X-linked choroideremia with progressive degeneration of photoreceptors, retinal pigment epithelium, and choroid. This analysis covers 941 CHM variants and mutations. Of these, 86% have computational variant effect predictions. Disease context includes choroideremia, Retinal dystrophy, and retinitis pigmentosa. Example CHM variants include M1I, M1T, and M1V.
