ClinGen PAH Variant Curation Expert Panel RCV001269043 SCV001448234 likely pathogenic Phenylketonuria 2024-11-17 reviewed by expert panel curation The c.1204T>C (p.Phe402Leu) variant in PAH has been detected in 1 Croatian patient with mild PKU, serum Phe = 600-1200 umol/L, BH4 deficiency not excluded (PMID: 12655552;PP4). This variant was detected with c.1169A>G (p.Glu390Gly) in this patient, reported as Pathogenic in ClinVar, VarID: 625, phase unknown (PMID: 12655552), and has also been reported in unknown phase with the pathogenic p.Arg408Gln variant (ClinVar ID: 577) in another individual with PAH deficiency (PMID: 32668217) (1pt total, PM3). This variant is absent from population databases (PM2_Supporting), and is predicted damaging by REVEL (REVEL score 0.918, PP3_Moderate). In summary, this variant meets criteria to be classified as likely pathogenic for phenylketonuria in an autosomal recessive manner based on the ACMG/AMP criteria applied as specified by the PAH Expert Panel: PM2_Supporting, PM3, PP3_Moderate, PP4.
