Analysis of allelic frequency stratified by type of parental history of T2D in males diagnosed early. A comparison of frequencies of risk and alternative alleles for SNPs in genes located in the chromosome region 11p15.5 (INS and KCNQ1) and TCF7L2 between cases and controls stratified by the type of parental history of T2D (mother only, father only, both parents). P-value was calculated with the Chi-squared test. SNP single nuclear polymorphism, T2D type 2 diabetes
