Description

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 544435). This premature translational stop signal has been observed in individual(s) with RYR1-related disease (Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu1740*) in the RYR1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RYR1 are known to be pathogenic (PMID: 20583297, 20839240, 23919265, 28818389).
