ARVD2

MIM.600996 1q42.1-q43

Friday 4 December 2009

Etiology

- Mutations in the cardiac ryanodine receptor gene (MIM.180902).

  • The ryanodine receptor on the sarcoplasmic reticulum is the major source of calcium required for cardiac muscle excitation-contraction coupling. The channel is a tetramer comprised of 4 RYR2 polypeptides and 4 FK506-binding proteins (FKBP1A; MIM.186945)
