Labcorp Genetics (formerly Invitae), Labcorp RCV000641586 SCV000763228 uncertain significance Aortic aneurysm, familial thoracic 4 2024-12-31 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 937 of the MYH11 protein (p.Arg937His). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with clinical features of MYH11-related conditions (internal data). ClinVar contains an entry for this variant (Variation ID: 534149). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt MYH11 protein function with a negative predictive value of 95%. 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.
Color Diagnostics, LLC DBA Color Health RCV001176624 SCV001340660 uncertain significance Familial thoracic aortic aneurysm and aortic dissection 2023-05-24 criteria provided, single submitter clinical testing This missense variant replaces arginine with histidine at codon 937 of the MYH11 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with MYH11-related disorders in the literature. This variant has been identified in 2/248594 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.
Fulgent Genetics, Fulgent Genetics RCV002499077 SCV002816717 uncertain significance Aortic aneurysm, familial thoracic 4; Visceral myopathy 2; Megacystis-microcolon-intestinal hypoperistalsis syndrome 2 2021-09-15 criteria provided, single submitter clinical testing
All of Us Research Program, National Institutes of Health RCV001176624 SCV004823535 uncertain significance Familial thoracic aortic aneurysm and aortic dissection 2024-08-29 criteria provided, single submitter clinical testing This missense variant replaces arginine with histidine at codon 937 of the MYH11 protein. 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 2/248594 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.
GeneDx RCV004723019 SCV005333720 uncertain significance not provided 2023-12-21 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function
