RCV001543656 | SCV001762334 | uncertain significance | Phenylketonuria | 2020-09-04 | reviewed by expert panel | curation | The c.1199+50G>A intronic variant has been reported homozygous in a Kurdish patient with classic PKU (PMID: 24048906), diagnosed by plasma Phe levels with BH4 deficiency excluded. However, this patient is also homozygous for c.441+1G>C (ClinVar 556894, Pathogenic). The c.1199+50G>A variant is present a low frequency in gnomAD with a MAF of 0.000008870 in the South Asian population but it is not highly conserved and is not predicted to have a deleterious effect. Splicing predictors are in consensus that there is no significant impact on splicing signals. In summary, this variant meets criteria to be classified as uncertain significance for PAH. PAH-specific ACMG/AMP criteria applied: PM2, BP7. |
