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]

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.65).

BP6

Variant 16-28898247-C-T is Benign according to our data. Variant chr16-28898247-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 318776.

BP7

Synonymous conserved (PhyloP=-1.59 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000499 (76/152224) while in subpopulation NFE AF = 0.000941 (64/68048). AF 95% confidence interval is 0.000755. There are 0 homozygotes in GnomAd4. There are 32 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR,AD gene
