CPVT=Catecholaminergic Ventricular Tachycardia; (1)-Associated with CPVT phenotype only in the homozygous carriers. Heterozygous patients showed normal phenotype. (2)-The proband was heterozygous; in this family the CASQ2-related disease could be autosomal dominant but with a mild phenotype and very low penetrance .(3)- Compund heterozygous with G112+5X; (4)- Seven consenguineous families. (5) Possible autosomal dominat transmission
