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 Benign. Variant got -12 ACMG points.

PP2

Missense variant in the RYR1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 212 curated pathogenic missense variants (we use a threshold of 10). The gene has 94 curated benign missense variants. Gene score misZ: 1.918 (below the threshold of 3.09). Trascript score misZ: 3.9788 (above the threshold of 3.09). GenCC associations: The gene is linked to 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.

BP4

Computational evidence support a benign effect (MetaRNN=0.01128754).

BP6

Variant 19-38483476-C-T is Benign according to our data. Variant chr19-38483476-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 159852.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=6, Benign=2, Uncertain_significance=1}. Variant chr19-38483476-C-T is described in Lovd as [Likely_benign]. Variant chr19-38483476-C-T is described in Lovd as [Benign].

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00539 (820/152208) while in subpopulation AFR AF= 0.0185 (769/41502). AF 95% confidence interval is 0.0174. There are 3 homozygotes in gnomad4. There are 389 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
