PreventionGenetics, part of Exact Sciences RCV003420323 SCV004117437 uncertain significance LAMA5-related disorder 2022-12-20 criteria provided, single submitter clinical testing The LAMA5 c.2659C>T variant is predicted to result in the amino acid substitution p.His887Tyr. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.31% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/20-60909322-G-A). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
Ambry Genetics RCV004632181 SCV005134513 likely benign Inborn genetic diseases 2024-05-20 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
GeneDx RCV003075492 SCV005688540 uncertain significance not provided 2024-07-30 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
