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 Likely_benign. Variant got -6 ACMG points.

PM1
In a domain B30.2/SPRY 2 (size 195) in uniprot entity RYR1_HUMAN there are 12 pathogenic changes around while only 3 benign (80%) in NM_000540.3
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=0.0110399425).
BP6
Variant 19-38469089-A-C is Benign according to our data. Variant chr19-38469089-A-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 256494.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=3, Uncertain_significance=3}.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000624 (95/152222) while in subpopulation AFR AF= 0.00207 (86/41538). AF 95% confidence interval is 0.00172. There are 1 homozygotes in gnomad4. There are 45 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
