摘要

Chondroitin sulfate (CS)/dermatan sulfate (DS) proteoglycans that play indispensable roles in multiple physiological processes, including cell proliferation, cell adhesion, development, neuronal guidance, and cartilage formation. Depletion of CS/DS caused by biosynthetic enzyme loss of function impairs these processes and results in embryonic lethality. However, some individuals with mutant enzymes survive and exhibit severe phenotypes. These rare hereditary diseases have been discovered and characterized in recent decades because of marked advances in next-generation sequencing technology. In this review, CS/DS-related inherited diseases caused by aberrations in both CS/DS backbone synthesis, as well as their sulfation and/or epimerization, are comprehensively summarized and their pathogenesis discussed.
