Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 27, 2023 | This sequence change creates a premature translational stop signal (p.Trp262*) in the FAH gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in FAH are known to be pathogenic (PMID: 9101289, 9633815). This variant is present in population databases (rs80338899, gnomAD 0.07%). This premature translational stop signal has been observed in individuals with tyrosinemia type I in Scandinavia (PMID: 7942842, 8162054, 8829657). ClinVar contains an entry for this variant (Variation ID: 11873). For these reasons, this variant has been classified as Pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Nov 12, 2019 | NM_000137.2(FAH):c.786G>A(W262*) is classified as pathogenic in the context of type I tyrosinemia. Sources cited for classification include the following: PMID 8723698, 8162054, 15465000, 7942842, 15638932 and 8829657. Classification of NM_000137.2(FAH):c.786G>A(W262*) is based on the following criteria: The variant causes a premature termination codon that is expected to be targeted by nonsense-mediated mRNA decay and is reported in individuals with the relevant phenotype. Please note: this variant was assessed in the context of healthy population screening. - |
