Genes affected

PFAS (HGNC:8863): (phosphoribosylformylglycinamidine synthase) Purines are necessary for many cellular processes, including DNA replication, transcription, and energy metabolism. Ten enzymatic steps are required to synthesize inosine monophosphate (IMP) in the de novo pathway of purine biosynthesis. The enzyme encoded by this gene catalyzes the fourth step of IMP biosynthesis. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=6.0514793E-7).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.8 is higher than 0.05.
