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 -19 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.25).
BP6
Variant 19-38457628-C-G is Benign according to our data. Variant chr19-38457628-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 256465.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-38457628-C-G is described in Lovd as [Benign].
BP7
Synonymous conserved (PhyloP=1.23 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00365 (555/152252) while in subpopulation AFR AF= 0.0127 (528/41542). AF 95% confidence interval is 0.0118. There are 3 homozygotes in gnomad4. There are 266 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 3 AD,AR gene
