Description

The c.913-8A>G PAH variant has been identified in at least one patient with classic PKU (PMID: 26666653). It was detected in trans with the pathogenic variant c.1315+1G>A (ClinVar 576). This variant is absent from 1000G, ESP, and gnomAD databases. In summary, this variant meets criteria to be classified as uncertain significance for PAH. PAH-specific ACMG/AMP criteria applied: PP4, PM2, PM3.
