Ambry Genetics RCV002458385 SCV002615137 uncertain significance Cardiovascular phenotype 2022-11-20 criteria provided, single submitter clinical testing The p.R1224Q variant (also known as c.3671G>A), located in coding exon 23 of the APOB gene, results from a G to A substitution at nucleotide position 3671. The arginine at codon 1224 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species, and glutamine is the reference amino acid in other vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Quest Diagnostics Nichols Institute San Juan Capistrano RCV003478467 SCV004218577 uncertain significance not provided 2023-06-19 criteria provided, single submitter clinical testing To the best of our knowledge, this variant has not been reported in the published literature. The frequency of this variant in the general population, 0.000098 (3/30616 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity.. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant.
