Genes affected

RYR3 (HGNC:10485): (ryanodine receptor 3) The protein encoded by this gene is a ryanodine receptor, which functions to release calcium from intracellular storage for use in many cellular processes. For example, the encoded protein is involved in skeletal muscle contraction by releasing calcium from the sarcoplasmic reticulum followed by depolarization of T-tubules. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with RYR3-related disease. This variant is present in population databases (rs761390620, ExAC 0.01%). This sequence change replaces aspartic acid with glutamic acid at codon 10 of the RYR3 protein (p.Asp10Glu). The aspartic acid residue is moderately conserved and there is a small physicochemical difference between aspartic acid and glutamic acid. -

RYR3 NM_001036.3 exon 1 p.Asp10Glu (c.30C>A): This variant has not been reported in the literature but is present in 0.002% (1/41432) of African alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/15-33311075-C-A?dataset=gnomad_r3). This variant is present in ClinVar (Variation ID:646212). Evolutionary conservation suggests that this variant may impact the protein; computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
