Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PP3PP4PM3_Strong

This summary comes from the ClinGen Evidence Repository: The c.283A>T (p.Ile95Phe) variant in PAH has been reported in multiple patients with mild and moderate phenylketonuria. It was detected with pathogenic variants: p.R408W (PMID:10495930); p.R158Q, p.A403V, p.T323del (PMID:18299955); and p.E280K (PMID:31623983). This variant has a MAF of 0.00060 in gnomAD in the Ashkenazi Jewish population, which is above our cutoff for PM2 (<0.0002) and below our cutoff for BS1 (>0.002). Computational evidence support a deleterious effect (REVEL=0.658). In summary, this variant meets criteria to be classified as likely pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PM3_strong, PP3, PP4. LINK:https://erepo.genome.network/evrepo/ui/classification/CA229507/MONDO:0009861/006

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]
