COL11A1 (Collagen alpha-1(XI) chain) variants and mutations

COL11A1 (also known as Collagen alpha-1(XI) chain) is a human protein-coding gene encoding a collagen alpha-1(XI) chain protein. A chain of type XI collagen, an extracellular-matrix protein found in cartilage and the eye. Variants can cause Stickler or Marshall syndrome. This analysis covers 2,685 COL11A1 variants and mutations. Of these, 93% have computational variant effect predictions. Disease context includes Stickler syndrome type 2, Marshall syndrome, and fibrochondrogenesis 1. Example COL11A1 variants include P3L, W4R, and S5F.
