GeneDx RCV000414515 SCV000492192 uncertain significance not specified 2016-12-07 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the APOB gene. The S4392N variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The S4392N variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Nevertheless, the S4392N variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is not conserved across species. Lastly, the majority of in silico analyses (2 out of 3) predict this variant likely does not alter the protein structure/function.
Invitae RCV000690044 SCV000817721 likely benign Familial hypercholesterolemia 2; Hypobetalipoproteinemia, familial, 1 2019-12-31 criteria provided, single submitter clinical testing
Illumina Clinical Services Laboratory,Illumina RCV001141496 SCV001301845 uncertain significance Hypobetalipoproteinemia, familial, 1 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
