Phenylketonuria VCEP

The c.745del (p.Leu249fs) variant in PAH has been reported in 1 Chilean patient with mild PKU; Phe = 600-900umol/L (PMID: 29288420; PP4). This variant was detected with V388M - reported at Pathogenic in ClinVar (VarID:610, 7 submitters); phase not confirmed - 0.5 points (PMID: 29288420; PM3_supporting). This frameshift variant is predicted to undergo NMD, not located in last exon or last 50bp of preliminary exon (Coding exon number 7 out of 13 coding exons; 7 out of total exons) (PVS1). This variant is absent from population databases (PM2). In summary, this variant meets criteria to be classified as pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PVS1, PM2, PP4, PM3_supporting.

PVS1

Frameshift variant, predicted to undergo NMD, not located in last exon or last 50bp of preliminary exon. Coding exon number 7 out of 13 coding exons (7 out of total exons).

PM2

PP4

PMID: 29288420 - L249fs detected in 1 Chilean patient with mild PKU; Phe = 600-900umol/L

PM3_Supporting

PMID: 29288420 - L249fs detected with V388M - reported at Pathogenic in ClinVar (VarID:610, 7 submitters); phase not confirmed - 0.5 points
