Variant summary

Our verdict is Pathogenic. The variant received 6 ACMG points: 6P and 0B. PM3PM2PP4_Moderate

This summary comes from the ClinGen Evidence Repository: The c.529G>C (p.Val177Leu) variant in PAH has been reported in multiple individuals with PAH deficiency (BH4 deficiency excluded). (PP4_Moderate). This variant has an extremely low allele frequency (Pop Max MAF=0.00005 ENF) in gnomAD (PM2). This variant was detected with pathogenic variants: F39L, L48S, F39del, R408W, R261Q, F55fs, R158Q, Trp187*. Parental testing not reported. PMID:8659548, PMID:16879198, PMID:19609714, PMID:23430918, PMID:22391997, PMID:22513348, PMID:26666653 (PM3_very-strong. Computational prediction tools and conservation analysis do not agree. In summary, this variant meets criteria to be classified as pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PP4_Moderate, PM3_very-strong, PM2.

Genes affected

PAH (HGNC:8582): (phenylalanine hydroxylase) This gene encodes a member of the biopterin-dependent aromatic amino acid hydroxylase protein family. The encoded phenylalanine hydroxylase enzyme hydroxylates phenylalanine to tyrosine and is the rate-limiting step in phenylalanine catabolism. Deficiency of this enzyme activity results in the autosomal recessive disorder phenylketonuria. [provided by RefSeq, Aug 2017]
