Illumina Laboratory Services, Illumina	RCV001100501	SCV001257023	uncertain significance	Hutchinson-Gilford syndrome	2017-04-28	criteria provided, single submitter	clinical testing	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.

Color Diagnostics, LLC DBA Color Health	RCV001186448	SCV001352851	uncertain significance	Cardiomyopathy	2020-02-21	criteria provided, single submitter	clinical testing	This missense variant replaces aspartic acid with glutamic acid at codon 446 of the lamin A/C proteins. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 1/240780 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
