Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP2PP3_ModeratePP5_Moderate
The NM_000540.3(RYR1):c.14582G>C(p.Arg4861Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R4861C) has been classified as Pathogenic.

RYR1-related disorder Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Oct 24, 2022 | For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg4861 amino acid residue in RYR1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 11709545, 12565913, 16621918, 17483490, 23394784, 23553484, 25521991, 25960145, 26684984). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 expected to disrupt RYR1 protein function. ClinVar contains an entry for this variant (Variation ID: 1066439). This missense change has been observed in individual(s) with clinical features of autosomal dominant RYR1-related myopathy (Invitae). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 4861 of the RYR1 protein (p.Arg4861Pro). - |
