COL6A3 (Collagen alpha-3(VI) chain) variants and mutations

COL6A3 (also known as Collagen alpha-3(VI) chain) is a human protein-coding gene encoding a collagen alpha-3(VI) chain protein. It forms part of collagen VI microfibrils that organize the extracellular matrix around muscle fibers and many other cells. Pathogenic variants can cause Bethlem or Ullrich-spectrum collagen VI myopathy and, in some alleles, isolated dystonia. This analysis covers 4,738 COL6A3 variants and mutations. Of these, 88% have computational variant effect predictions. Disease context includes Congenital muscular dystrophy, Ullrich type, dystonia 27, and Bethlem myopathy. Example COL6A3 variants include M1?, R2K, and K3N.
