Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV004800872 SCV005422839 pathogenic Acute infantile liver failure due to synthesis defect of mtDNA-encoded proteins 2024-10-16 criteria provided, single submitter clinical testing Variant summary: NBAS c.1284G>A (p.Trp428X) 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. The variant allele was found at a frequency of 4e-06 in 251366 control chromosomes (gnomAD). To our knowledge, To our knowledge, no occurrence of c.1284G>A in individuals affected with Liver Failure Acute Infantile, Type 2 and no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 31964843). No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as pathogenic.
