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]

Review Status:reviewed by expert panel

Collection Method:curation

The c.442-18G>A variant in PAH has not been reported in the literature to our knowledge. This variant has a MAF of 0.00067 in the gnomAD Latino population. This is too high for PM2, but too low for BS1 per PAH EP guidelines. No splicing impact is predicted in HSF or MaxEnt (BP7). In summary, this variant meets criteria to be classified as uncertain significance for PAH. PAH-specific ACMG/AMP criteria applied: BP7. -
