COL4A5 (Collagen alpha-5(IV) chain) variants and mutations

COL4A5 (also known as Collagen alpha-5(IV) chain) is a human protein-coding gene encoding a collagen alpha-5(IV) chain protein. It is essential for the alpha3-alpha4-alpha5 type IV collagen network that gives glomerular and cochlear basement membranes their mature mechanical properties. Pathogenic variants cause X-linked Alport syndrome, with progressive kidney disease, hearing loss, and characteristic ocular findings. This analysis covers 2,801 COL4A5 variants and mutations. Of these, 65% have computational variant effect predictions. Disease context includes X-linked Alport syndrome, Alport syndrome, and Dupuytren Contracture. Example COL4A5 variants include M1I, M1K, and M1V.
