Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 2P and 7B. PM1BP4_ModerateBP6BS1

The NM_000540.3(RYR1):​c.10564C>A​(p.Leu3522Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000595 in 1,613,490 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. L3522L) has been classified as Likely benign.

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: Likely_benign. The variant received -5 ACMG points.

PM1
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 9 uncertain in NM_000540.3
BP4
Computational evidence support a benign effect (MetaRNN=0.07121703).
BP6
Variant 19-38525440-C-A is Benign according to our data. Variant chr19-38525440-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 159827.
BS1
Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000643 (94/1461856) while in subpopulation AMR AF = 0.00208 (93/44718). AF 95% confidence interval is 0.00174. There are 0 homozygotes in GnomAdExome4. There are 32 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
