S126L | naturally occuring mutation, inactive mutant, the amount of chondroitin sulfate proteoglycans is reduced. In men, multiple sclerosis patients with S126L have a slower disease progression. This cSNP might be associated with the gender differences in clinical course of multiple sclerosis | Homo sapiens |

malfunction | missense mutations in the ChGn-1 gene results in an altered amount of chondroitin sulfate proteoglycans | Homo sapiens |
physiological function | chondroitin sulfate synthase 1 (CHSY1) is the key biosynthetic enzyme forming the repeating chondroitin sulfate backbone disaccharide structure [4GlcAbeta1-3GalNAcbeta1], and polymerization of chondroitin chain by CHSY1 requires chondroitin polymerizing factors, including CHPF and CHPF2. The bifunctional enzyme CHSY1 exhibits both GlcAT-II and GalNAc-II activities | Homo sapiens |
