Genes affected

PAPSS1 (HGNC:8603): (3'-phosphoadenosine 5'-phosphosulfate synthase 1) Three-prime-phosphoadenosine 5-prime-phosphosulfate (PAPS) is the sulfate donor cosubstrate for all sulfotransferase (SULT) enzymes (Xu et al., 2000 [PubMed 10679223]). SULTs catalyze the sulfate conjugation of many endogenous and exogenous compounds, including drugs and other xenobiotics. In humans, PAPS is synthesized from adenosine 5-prime triphosphate (ATP) and inorganic sulfate by 2 isoforms, PAPSS1 and PAPSS2 (MIM 603005).[supplied by OMIM, Mar 2008]

The c.1627G>T (p.A543S) alteration is located in exon 11 (coding exon 11) of the PAPSS1 gene. This alteration results from a G to T substitution at nucleotide position 1627, causing the alanine (A) at amino acid position 543 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
