Variant summary
Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BA1
This summary comes from the ClinGen Evidence Repository: This pathogenicity assessment is relevant only for malignant hyperthermia susceptibility (MHS) inherited in an autosomal dominant pattern. Variants in RYR1 can also cause other myopathies inherited in an autosomal dominant pattern or in an autosomal recessive pattern. Some of these disorders may predispose individuals to malignant hyperthermia. RYR1 variants may also contribute to a malignant hyperthermia reaction in combination with other genetic and non-genetic factors and the clinician needs to consider such factors in making management decisions.This sequence variant predicts a substitution of Serine with Glycine at codon 1342 of the RYR1 protein, p.(Ser1342Gly). The maximum allele frequency for this variant among the six major gnomAD populations is AFR: 0.1566, which is considered to be too common for a pathogenic variant causing autosomal dominantly inherited MHS, BA1. This variant has been classified as Benign. Criteria implemented: BA1. LINK:https://erepo.genome.network/evrepo/ui/classification/CA024415/MONDO:0007783/012

Benign, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Mar 06, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. - |
