Phenylketonuria VCEP

The c.911A>G (p.Gln304Arg) variant in PAH has been reported in multiple individuals with PKU (BH4 deficiency excluded). (PP4_Moderate; PMID: 8632937, 22841515, 30747360). This variant is absent in population databases (PM2). This variant was detected with pathogenic variant p.R252W (PM3_supporting). Computational evidence supports a deleterious effect. In summary, this variant meets criteria to be classified as likely pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PP4_Moderate, PM2, PM3_supporting, PP3.

PM3_Supporting

Detected with pathogenic variant R252W (5 submitters); parental analysis not reported

PP3

Predicted deleterious in SIFT, PolyPhen2, MutationTaster. REVEL=0.98

PM2

Absent from controls in ExAC, gnomAD, 1000 Genomes, ESP

PP4_Moderate

detected in 3 patients, one with severe PKU (PMID: 8632937, 22841515); 1 with classical PKU BH4 deficiency ruled out (PMID: 30747360)
