Evidence submitted by expert panel

Phenylketonuria VCEP

The c.656T>C (p.Phe219Ser) variant in PAH has been reported in a Chinese patient with PAH deficiency (referred to as P219S, BH4 deficiency excluded, PMID 21307867). This variant is absent from population databases. Multiple lines of computational evidence support a deleterious effect . In summary, this variant meets criteria to be classified as uncertain significance for PAH. PAH-specific ACMG/AMP criteria applied: PP4_Moderate, PM2, PP3.

PP4_Moderate

PMID 21307867: (referred to as P219S) c.656T>C in a patient cohort with Phe level higher than 0.18mM. analysis of dihydropteridine reductase activity in red blood cells, biopterin loading test and/or pteridine analysis in urine performed.

PMID 21307867: listed as P219S c.656T>C in Table 2. A patient cohort with Phe level higher than 0.18mM PubMed:21307867

PP3

Predicted deleterious in SIFT, PolyPhen2, MutationTaster. REVEL=0.901

PM2

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