Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM2 PP4 PM4 PM3

This summary comes from the ClinGen Evidence Repository: The c.1092_1106del (p.Leu365_Leu369del) variant in PAH has been reported in 1 individual with PKU (PP4; PMID:1363837) in trans with pathogenic variant p.R408W (PM3). This variant is absent in population databases (PM2). This variant is a 15 bp in-frame deletion in exon 11 (PM4). In summary, this variant meets criteria to be classified as likely pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PP4, PM2, PM3, PM4.

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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.
