Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3
The NM_000540.3(RYR1):c.6023T>A(p.Met2008Lys) variant causes a missense change. The variant allele was found at a frequency of 0.00000125 in 1,601,906 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. M2008T) has been classified as Uncertain significance.

RYR1-related disorder Uncertain:1
This variant is present in population databases (no rsID available, gnomAD 0.002%). 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. 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 RYR1 protein function. This variant has not been reported in the literature in individuals affected with RYR1-related conditions. This sequence change replaces methionine, which is neutral and non-polar, with lysine, which is basic and polar, at codon 2008 of the RYR1 protein (p.Met2008Lys). -
