Criteria Specification Information

Evidence submitted by expert panel

Phenylketonuria VCEP

The c.1163_1164del (p.Val388fs) variant in PAH has been reported in 1 female patient with classic PKU, Phe = 1210umol/L; BH4 deficiency not excluded (PMID: 10200057; PP4). This frameshift variant is predicted to undergo NMD, not located in last exon or last 50bp of preliminary exon. Coding exon number 11 out of 13 coding exons (11 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.

Met criteria codes

• PP4: PMID: 10200057 - V388fs detected in 1 female patient with classic PKU, Phe = 1210umol/L; BH4 deficiency not excluded
• PM2: Variant absent from population databases.
• PVS1: Frameshift variant, predicted to undergo NMD, not located in last exon or last 50bp of preliminary exon. Coding exon number 11 out of 13 coding exons (11 out of total exons).
