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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 03, 2022The c.277G>C (p.E93Q) alteration is located in exon 3 (coding exon 1) of the TPST2 gene. This alteration results from a G to C substitution at nucleotide position 277, causing the glutamic acid (E) at amino acid position 93 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
