Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong
The NM_000277.3(PAH):c.728G>T(p.Arg243Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R243Q) has been classified as Likely pathogenic.

Likely pathogenic, reviewed by expert panel | curation | ClinGen PAH Variant Curation Expert Panel | Feb 14, 2021 | The c.728G>T (p.Arg243Leu) variant in PAH has been reported in 1 individual with PKU detected with pathogenic variant p.R261Q (P 9 submitters) PMID: 12655553, 20217238. This variant is absent in population databases. Computational evidence supports a deleterious effect. Another missense change at the same amino acid,p .Arg243Gln, is pathogenic in ClinVar by multiple submitters (variation ID 591). In summary, this variant meets criteria to be classified as likely pathogenic for PAH. PAH-specific ACMG/AMP criteria applied: PP4, PM2, PM3, PM5, PP3. - |
