Athena Diagnostics Inc RCV000712227 SCV000842670 uncertain significance not provided 2018-04-30 criteria provided, single submitter clinical testing
Illumina Clinical Services Laboratory,Illumina RCV001098489 SCV001254860 uncertain significance Lipoatrophy with Diabetes, Hepatic Steatosis, Hypertrophic Cardiomyopathy, and Leukomelanodermic Papules 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.

Invitae RCV001372393 SCV001569042 uncertain significance Charcot-Marie-Tooth disease, type 2 2020-02-21 criteria provided, single submitter clinical testing This sequence change replaces alanine with valine at codon 318 of the LMNA protein (p.Ala318Val). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and valine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with hereditary motor neuropathy (PMID: 26392352). ClinVar contains an entry for this variant (Variation ID: 586129). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: Deleterious; PolyPhen-2: Benign; Align-GVGD: Class C5). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
