About CASQ2

Cytogenetic location: 1p13.1 Genomic coordinates (GRCh38): 1:115,700,021-115,768,714 (from NCBI)

This gene has 2 transcripts (splice variants), 276 orthologues, 1 paralogue and is associated with 4 phenotypes. Biased expression in heart (RPKM 404.6), urinary bladder (RPKM 24.0) and 2 other tissues.

Summary

The protein encoded by this gene specifies the cardiac muscle family member of the calsequestrin family. Calsequestrin is localized to the sarcoplasmic reticulum in cardiac and slow skeletal muscle cells. The protein is a calcium binding protein that stores calcium for muscle function. Mutations in this gene cause stress-induced polymorphic ventricular tachycardia, also referred to as catecholaminergic polymorphic ventricular tachycardia 2 (CPVT2), a disease characterized by bidirectional ventricular tachycardia that may lead to cardiac arrest.
