Variant summary

Our verdict is Benign. Variant got -15 ACMG points: 1P and 16B. PP2BP4_StrongBP6_Very_StrongBS2

The NM_000540.3(RYR1):​c.3946C>A​(p.Pro1316Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00115 in 1,599,518 control chromosomes in the GnomAD database, including 26 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P1316L) 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 made for transcript

Verdict is Benign. Variant got -15 ACMG points.

PP2
Missense variant in the RYR1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 212 curated pathogenic missense variants (we use a threshold of 10). The gene has 94 curated benign missense variants. Gene score misZ: 1.918 (below the threshold of 3.09). Trascript score misZ: 3.9788 (above the threshold of 3.09). GenCC associations: The gene is linked to 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=0.008618742).
BP6
Variant 19-38473557-C-A is Benign according to our data. Variant chr19-38473557-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 544494.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS2
High Homozygotes in GnomAd4 at 8 AD,AR gene
