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: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.8).
BP6
Variant 19-38446571-G-A is Benign according to our data. Variant chr19-38446571-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 218467.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.00112 (171/152340) while in subpopulation AMR AF = 0.00209 (32/15302). AF 95% confidence interval is 0.00152. There are 2 homozygotes in GnomAd4. There are 72 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 2 AR,AD gene
