Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_001006630.2(CHRM2):c.1030G>A(p.Val344Met) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000167 in 1,612,994 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. V344G) has been classified as Uncertain significance.

Dilated Cardiomyopathy, Dominant Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Apr 29, 2023 | 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant  is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 478111). This variant has not been reported in the literature in individuals affected with CHRM2-related conditions. This variant is present in population databases (rs201165506, gnomAD 0.006%). This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 344 of the CHRM2 protein (p.Val344Met). - |
