Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 2P and 9B. PM1BP4_StrongBP6BS1

The NM_000540.3(RYR1):c.3505A>C(p.Met1169Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000148 in 1,614,112 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M1169V) has been classified as Uncertain significance.

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 -7 ACMG points.

PM1

In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 13 uncertain in NM_000540.3

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 VariationId is 256494.

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 the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
