Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP2PP3

The NM_000540.3(RYR1):​c.13513G>T​(p.Asp4505Tyr) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000695 in 1,438,912 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D4505H) has been classified as Likely benign.

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 4 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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.831
