Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM5BP4_StrongBS1_Supporting

The NM_000540.3(RYR1):c.2366G>A(p.Arg789Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000114 in 1,614,052 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R789W) has been classified as Uncertain significance.

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 -3 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr19-38460380-G-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 2736874.Status of the report is criteria_provided_single_submitter, 1 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.050638497).

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.000114 (167/1461830) while in subpopulation AMR AF = 0.00286 (128/44724). AF 95% confidence interval is 0.00246. There are 0 homozygotes in GnomAdExome4. There are 75 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
