Invitae RCV000633482 SCV000754715 pathogenic Adrenoleukodystrophy 2017-10-31 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Gly607Alafs*28) in the ABCD1 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in ABCD1 are known to be pathogenic (PMID: 11748843). This variant has not been reported in the literature in individuals with ABCD1-related disease.
Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000633482 SCV001554538 likely pathogenic Adrenoleukodystrophy 2021-03-29 criteria provided, single submitter clinical testing Variant summary: ABCD1 c.1820_1823delGTGG (p.Gly607AlafsX28) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 162474 control chromosomes (gnomAD). To our knowledge, no occurrence of c.1820_1823delGTGG in individuals affected with Adrenoleukodystrophy and no experimental evidence demonstrating its impact on protein function have been reported. One ClinVar submitter (evaluation after 2014) cites the variant as pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic.
