NCIt definition : Human JPH2 wild-type allele is located in the vicinity of 20q13.12 and is approximately
81 kb in length. This allele, which encodes junctophilin-2 protein, plays a role in
the coupling of excitation and contraction in cardiomyocytes and the response to cardiac
stress. Mutation in the gene is associated in both dilated cardiomyopathy 2E and hypertrophic
