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 made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RYR1. . Gene score misZ 1.918 (greater than the threshold 3.09). Trascript score misZ 3.9788 (greater than threshold 3.09). GenCC has associacion of gene with King-Denborough syndrome, congenital multicore myopathy with external ophthalmoplegia, autosomal recessive centronuclear myopathy, RYR1-related myopathy, lethal multiple pterygium syndrome, malignant hyperthermia of anesthesia, benign Samaritan congenital myopathy, malignant hyperthermia, susceptibility to, 1, congenital myopathy with myasthenic-like onset, central core myopathy.
