Phenylketonuria VCEP

The c.1102G>A (p.Glu368Lys) variant in PAH has been reported in 1 individual with moderate PKU (BH4 deficiency excluded). (PP4_Moderate; PMID: 31355225). This variant has extremely low frequency in gnomAD: MAF=0.00001 (PM2). This variant was detected in trans with pathogenic variant c.1066-11G>A. Parents were also investigated to confirm their carrier status. (PM3). Computational evidence is conflicting. In summary, this variant meets criteria to be classified as likely pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PP4_Moderate, PM2, PM3.

PM2

extremely low frequency in gnomAD. MAF=0.00001

PM3

Detected in trans with pathogenic variant c.1066-11G>A. Parents were also investigated to confirm their carrier status.

PP4_Moderate

Detected in a patient with moderate PKU (Phe levels 9.5 mg/dL), Bh4 deficiency ruled out with urinary pterin analysis, and determination of DHPR activity. PMID: 31355225

PubMed:31355225

PP3

Computational evidence is conflicting: deleterious in SIFT, MutationTaster; benign in PolyPhen2, REVEL=0.711.

PM5

The current variant is the only variant found in this codon in ClinVar.
