Description

In affected members of a 4-generation Han Chinese family with autosomal dominant cardiac arrhythmias and sudden death (BRGDA1; 601144), Niu et al. (2006) identified heterozygosity for a G-A transition in exon 24 of the SCN5A gene, resulting in a trp1421-to-ter (W1421X) substitution. The mutation was not found in 95 control subjects. An asymptomatic 73-year-old male family member was found to be compound heterozygous for W1421X and the R1993Q mutation (600163.0023). Niu et al. (2006) suggested that R1193Q, which results in a gain of sodium channel function, may compensate for the deleterious effects of W1421X.
