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.

The c.485C>T (p.T162M) alteration is located in exon 3 (coding exon 1) of the TPST2 gene. This alteration results from a C to T substitution at nucleotide position 485, causing the threonine (T) at amino acid position 162 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
