The association of rs1008832 CACNA1C, rs4027402 SYNE2, rs2340917 TMEM43, rs58225473 CACNB2 with sudden cardiac death

Single nucleotide polymorphisms rs1008832 of the CACNA1C gene, rs4027402 of the SYNE2 gene, rs2340917 of the TMEM43 gene, rs58225473 of the CACNB2 gene were found by sequencing the clinical exome of a group of men who died of sudden cardiac death (SCD) at the age of 45 years. The aim of the study is to study the association of single nucleotide polymorphisms rs1008832 of the CACNA1C gene, rs4027402 of the SYNE2 gene, rs2340917 of the TMEM43 gene, rs58225473 of the CACNB2 gene with SCD in a case-control study using routine molecular genetic analysis. 
Material and methods. SCD group (n = 400, mean age 53.2 ± 8.7 years, 70.9 % men, 29.1 % women) was formed using the SCD criteria of the European Society of Cardiology from the anonymous DNA bank of the deceased sudden death (1999–2019). The control group (n = 400, mean age 53.1 ± 8.3 years, 68.3 % men, 31.7 % women) was matched by sex and age to the SCD group from DNA banks of international projects MONICA and HAPIEE of living at the time of researches participants. Genotyping was carried out using the polymerase chain reaction followed by analysis of restriction fragment length polymorphism. 
Results. There were no statistically significant differences in the frequencies of genotypes and alleles of single nucleotide polymorphisms rs1008832 of the CACNA1C gene, rs4027402 of the SYNE2 gene, rs2340917 of the TMEM43 gene, rs58225473 of the CACNB2 gene between the SCD group and the control group (p > 0.05). 
Conclusions. The association of single nucleotide rs1008832 of the CACNA1C gene, rs4027402 of the SYNE2 gene, rs2340917 of the TMEM43 gene, rs58225473 of the CACNB2 gene with SCD has not been confirmed.
