Green List (high evidence)

GALNT3 is one of several enzymes that catalyze the reaction UDP-GalNAc + polypeptide-(Ser/Thr)-OH to GalNAc-alpha-O-Ser/Thr-polypeptide + UDP, thereby initiating O-glycosylation of serine and threonine residues on an array of glycoproteins.

Hyperphosphatemic familial tumoral calcinosis is a rare autosomal recessive metabolic disorder characterised by the progressive deposition of basic calcium phosphate crystals in periarticular spaces, soft tissues, and sometimes bone. More than 5 unrelated families reported.
