Illumina Clinical Services Laboratory,Illumina RCV001094654 SCV000427188 likely benign Familial hypercholesterolemia 2 2018-01-12 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 and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.
Illumina Clinical Services Laboratory,Illumina RCV000344371 SCV000427189 uncertain significance Hypobetalipoproteinemia, familial, 1 2018-01-12 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.
GeneDx RCV000522955 SCV000619075 uncertain significance not provided 2017-07-13 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the APOB gene. The Q96H variant has been reported in three Chinese patients referred for coronary angiography and subsequently diagnosed with FH (Li et al., 2017); however, additional clinical information was not provided. This variant is observed in 0.54%-1% alleles from individuals of East Asian background in large population cohorts, which is greater than expected for this disorder (Lek et al., 2016; McVean et al., 2012; Exome Variant Server). This substitution occurs at a position that is not conserved across species and where histidine (H) is present as the wild type in at least one species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Nevertheless, the Q96H variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties.
