Labcorp Genetics (formerly Invitae), Labcorp RCV002903025 SCV003248854 pathogenic Hereditary hyperferritinemia with congenital cataracts; Neuroferritinopathy 2022-06-01 criteria provided, single submitter clinical testing This sequence change results in a frameshift in the FTL gene (p.Arg154Profs*27). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 22 amino acid(s) of the FTL protein and extend the protein by 4 additional amino acid residues. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FTL-related conditions. This variant results in an extension of the FTL protein. Other variant(s) that result in a similarly extended protein product (p.Arg154Lysfs*27) have been determined to be pathogenic (PMID: 11438811, 19781644). This suggests that these extensions are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
