Invitae RCV000693354 SCV000821220 uncertain significance Charcot-Marie-Tooth disease type 2 2022-08-31 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 500476). This variant has not been reported in the literature in individuals affected with LMNA-related conditions. This variant is present in population databases (rs746056534, gnomAD 0.003%). This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 285 of the LMNA protein (p.Val285Leu).
Color Diagnostics, LLC DBA Color Health RCV001189490 SCV001356797 uncertain significance Cardiomyopathy 2019-09-18 criteria provided, single submitter clinical testing This missense variant replaces valine with leucine at codon 285 of the LMNA protein. Computational prediction tool is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 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 1/251086 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.
