Variant summary

Our verdict is Pathogenic. The variant received 7 ACMG points: 7P and 0B. PP3PM3PM2PP4_Moderate

This summary comes from the ClinGen Evidence Repository: The c.1157A>G (p.Tyr386Cys) variant in PAH has been reported in multiple probands with PKU (BH4 deficiency excluded) (PMID:16198137; PP4_Moderate). This variant has been detected with c.1315+1G>A, R252W, L311P, R261Q, I65V, Q178G, R158Q (all reported as Pathogenic in ClinVar, 4.0 points total) (PMIDs:24368688, 24941924, 22841515, 16198137, 26210745, 23357515, 18493213; PM3_very-strong). This variant is absent from population databases (PM2) and is predicted deleterious by SIFT, PolyPhen2, MutationTaster, and REVEL = 0.975 (PP3). In summary, this variant meets criteria to be classified as pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PM3_very-strong, PM2, PP4_Moderate, PP3.

Genes affected

PAH (HGNC:8582): (phenylalanine hydroxylase) This gene encodes a member of the biopterin-dependent aromatic amino acid hydroxylase protein family. The encoded phenylalanine hydroxylase enzyme hydroxylates phenylalanine to tyrosine and is the rate-limiting step in phenylalanine catabolism. Deficiency of this enzyme activity results in the autosomal recessive disorder phenylketonuria. [provided by RefSeq, Aug 2017]
