Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 1P and 1B. PP2BP4
The NM_002474.3(MYH11):c.5210G>A(p.Arg1737Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000626 in 1,596,380 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1737W) has been classified as Uncertain significance.

Familial thoracic aortic aneurysm and aortic dissection Uncertain:3
Uncertain significance, criteria provided, single submitter | clinical testing | CHEO Genetics Diagnostic Laboratory, Children's Hospital of Eastern Ontario | Mar 18, 2020 | - - |
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Nov 06, 2022 | This missense variant replaces arginine with glutamine at codon 1744 of the MYH11 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, 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 2/225748 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 24, 2022 | The p.R1737Q variant (also known as c.5210G>A), located in coding exon 36 of the MYH11 gene, results from a G to A substitution at nucleotide position 5210. The arginine at codon 1737 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
Aortic aneurysm, familial thoracic 4 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 08, 2023 | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1744 of the MYH11 protein (p.Arg1744Gln). 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 variant has not been reported in the literature in individuals affected with MYH11-related conditions. ClinVar contains an entry for this variant (Variation ID: 581863). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt MYH11 protein function. 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. - |
