Abstract: The invention provides a sudden cardiac death susceptibility detection kit based on an insertion/deletion polymorphic site of COX10 gene. A specific primer pair contained in the kit is designed for the insertion/deletion site rs397763766 on the COX10 gene. DNA fragments containing the site are specifically amplified. Different genotypes are recognized by detecting the mobility of fragments different in length in capillary electrophoresis. In combination with findings in a case-control study, it is believed that an individual carrying a deletion-type allele at the insertion/deletion site rs397763766 of COX10 gene in the detected DNA is SCD susceptible. Therefore, the SCD susceptibility of an individual is predicted by detecting the genotype of the insertion/deletion site rs397763766 on the COX10 gene in the individual. It is confirmed that a two-base (CT) insertion/deletion polymorphism (rs397763766) located in the 3?UTR of the COX10 gene is significantly associated with the risk of suffering from SCD.
