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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP3
Nonframeshift variant in repetitive region in NM_000540.3
BS1
Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.000265 (387/1460912) while in subpopulation SAS AF = 0.00147 (127/86230). AF 95% confidence interval is 0.00126. There are 0 homozygotes in GnomAdExome4. There are 220 alleles in the male GnomAdExome4 subpopulation. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
