Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM1PP2BP4_Strong

The NM_000540.3(RYR1):c.3108C>A(p.Asp1036Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000443 in 1,603,780 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict 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. D1036D) 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 made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM1

In a domain B30.2/SPRY 2 (size 195) in uniprot entity RYR1_HUMAN there are 23 pathogenic changes around while only 8 benign (74%) in NM_000540.3

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RYR1. . Gene score misZ 1.918 (greater than the threshold 3.09). Trascript score misZ 3.9788 (greater than threshold 3.09). GenCC has associacion of gene with King-Denborough syndrome, congenital multicore myopathy with external ophthalmoplegia, autosomal recessive centronuclear myopathy, RYR1-related myopathy, lethal multiple pterygium syndrome, malignant hyperthermia of anesthesia, benign Samaritan congenital myopathy, malignant hyperthermia, susceptibility to, 1, congenital myopathy with myasthenic-like onset, central core myopathy.

BP4

Computational evidence support a benign effect (MetaRNN=0.039546937).
