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 GeneticsMay 28, 2024The c.512G>A (p.R171H) 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 512, causing the arginine (R) at amino acid position 171 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
