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

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 19-38500760-T-G is Benign according to our data. Variant chr19-38500760-T-G is described in ClinVar as [Likely_benign]. Clinvar id is 256551.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00146 (223/152260) while in subpopulation AFR AF= 0.00508 (211/41570). AF 95% confidence interval is 0.00451. There are 1 homozygotes in gnomad4. There are 92 alleles in male gnomad4 subpopulation. This position pass quality control queck.
