COL5A2 (Collagen alpha-2(V) chain) variants and mutations

COL5A2 (also known as Collagen alpha-2(V) chain) is a human protein-coding gene encoding a collagen alpha-2(V) chain protein. It partners with COL5A1-derived chains to regulate collagen fibril formation in skin, tendons, and other connective tissues. Pathogenic variants can cause classical Ehlers-Danlos syndrome with tissue fragility, hyperextensible skin, and joint hypermobility. This analysis covers 2,248 COL5A2 variants and mutations. Of these, 69% have computational variant effect predictions. Disease context includes Ehlers-Danlos syndrome, classic type, Ehlers-Danlos syndrome, classic type, 2, and Ehlers-Danlos syndrome, classic type, 1. Example COL5A2 variants include M1?, M2T, and M2V.
