Genes affected

ATP2A1 (HGNC:811): (ATPase sarcoplasmic/endoplasmic reticulum Ca2+ transporting 1) This gene encodes one of the SERCA Ca(2+)-ATPases, which are intracellular pumps located in the sarcoplasmic or endoplasmic reticula of muscle cells. This enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen, and is involved in muscular excitation and contraction. Mutations in this gene cause some autosomal recessive forms of Brody disease, characterized by increasing impairment of muscular relaxation during exercise. Alternative splicing results in three transcript variants encoding different isoforms. [provided by RefSeq, Oct 2013]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jul 06, 2022	This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 37 of the ATP2A1 protein (p.Gly37Ser). This variant is present in population databases (rs200428113, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with ATP2A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 464069). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -

The c.109G>A (p.G37S) alteration is located in exon 1 (coding exon 1) of the ATP2A1 gene. This alteration results from a G to A substitution at nucleotide position 109, causing the glycine (G) at amino acid position 37 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
