NM_000540.3:c.9093C>T

Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4BP7BS1

This summary comes from the ClinGen Evidence Repository: The c.9093C>T (p.Ala3031=) variant (NM_000540.3(RYR1):c.9093C>T (p.Ala3031=)) in RYR1 is a synonymous (silent) variant that is not predicted by Splice AI to impact splicing. In addition, it occurs at a nucleotide that is not conserved as shown by UCSC genome browser (BP4, BP7). The filtering allele frequency (the lower threshold of the 95% CI of 3/6084) of the c.9093C>T variant in RYR1 is 0.0001414 for Middle Eastern chromosomes by gnomAD v4.1, which is higher than the ClinGen Congenital Myopathies VCEP threshold (≥0.0000006) for BS1, and therefore meets this criterion (BS1). In summary, this variant meets the criteria to be classified as likely benign for RYR1-related myopathy, based on the ACMG/AMP criteria applied, as specified by the ClinGen Congenital Myopathies VCEP: BS1, BP4, BP7 (Congenital Myopathies VCEP Specifications Version 1; 8/7/2024).

Genes affected
RYR1 (HGNC:10483): (ryanodine receptor 1) This gene encodes a ryanodine receptor found in skeletal muscle. The encoded protein functions as a calcium release channel in the sarcoplasmic reticulum but also serves to connect the sarcoplasmic reticulum and transverse tubule. Mutations in this gene are associated with malignant hyperthermia susceptibility, central core disease, and minicore myopathy with external ophthalmoplegia. Alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
