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]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.06052178).

Nov 17, 2022

The c.1855A>C (p.K619Q) alteration is located in exon 12 (coding exon 12) of the PAPSS1 gene. This alteration results from a A to C substitution at nucleotide position 1855, causing the lysine (K) at amino acid position 619 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
