Illumina Laboratory Services, Illumina	RCV000314471	SCV000427054	uncertain significance	Hypercholesterolemia, autosomal dominant, type B	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.

GENinCode PLC	RCV004820021	SCV005441647	likely benign	Familial hypercholesterolemia	2023-03-31	criteria provided, single submitter	clinical testing	This is a synonymous (silent) variant that is not predicted by SpliceAI to impact splicing. In addition, it occurs at a nucleotide that is not conserved. Therefore this variant has been classified as Likely Benign (BP4, BP7).
