Ambry Genetics | RCV002313445 | SCV000739325 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2017-03-06 | criteria provided, single submitter | clinical testing | The p.A1176T variant (also known as c.3526G>A), located in coding exon 16 of the MYLK gene, results from a G to A substitution at nucleotide position 3526. The alanine at codon 1176 is replaced by threonine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
Invitae | RCV001055876 | SCV001220290 | uncertain significance | Aortic aneurysm, familial thoracic 7 | 2023-09-09 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 1176 of the MYLK protein (p.Ala1176Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MYLK-related conditions. ClinVar contains an entry for this variant (Variation ID: 520004). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on MYLK 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. |

RCV001775926 | SCV002012769 | uncertain significance | not provided | 2019-04-15 | criteria provided, single submitter | clinical testing | Has not been previously published as pathogenic or benign to our knowledge; Not observed in large population cohorts (Lek et al., 2016); Reported in ClinVar as a variant of uncertain significance (ClinVar Variant ID# 520004; Landrum et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function |
