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]

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.17734501).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000408 (62/152088) while in subpopulation AFR AF= 0.00145 (60/41430). AF 95% confidence interval is 0.00115. There are 0 homozygotes in gnomad4. There are 29 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

Brody myopathy Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 03, 2022This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 820 of the ATP2A1 protein (p.Pro820Thr). This variant is present in population databases (rs149282970, gnomAD 0.2%). 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: 390036). 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: "Tolerated"; PolyPhen-2: "Possibly 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. -

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2023The c.2458C>A (p.P820T) alteration is located in exon 17 (coding exon 17) of the ATP2A1 gene. This alteration results from a C to A substitution at nucleotide position 2458, causing the proline (P) at amino acid position 820 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
