Genes affected

TPST2 (HGNC:12021): (tyrosylprotein sulfotransferase 2) The protein encoded by this gene catalyzes the O-sulfation of tyrosine residues within acidic regions of proteins. The encoded protein is a type II integral membrane protein found in the Golgi body. Alternative splicing produces multiple transcript variants encoding distinct isoforms.

May 20, 2024

The c.188G>A (p.R63H) alteration is located in exon 3 (coding exon 1) of the TPST2 gene. This alteration results from a G to A substitution at nucleotide position 188, causing the arginine (R) at amino acid position 63 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
