Single nucleotide polymorphisms (SNPs) of non-coding RNA in the INK4 locus (ANRIL) have been found to be associated with myocardial infarction (MI). However, the effect of rs1333049:C>G in INK4 locus in familial hypercholesterolemia patients and on lipid profile of the patients has not been studied in Pakistan. We therefore investigated the association of SNP rs1333049:C>G with MI as well as familial hypercholesterolemia patients and also determined the effect of genotype on lipid levels in a northern Pakistani population. A case-control association study was performed in which 611 individuals (294 patients, 290 healthy controls and 27 patients from hypercholesterolemia families) were genotyped for rs1333049:C>G, using an Allele specific polymerase chain reaction. We found a significant association of rs1333049:C>G with MI (chi(2)=22.3, p<0.001). The frequency of risk genotype CC was significantly different from the healthy controls (p<0.001, chi(2)=223). The risk allele C was at a higher frequency in the MI patients as compared to the controls (odds ratio [OR]=1.55 (95% confidence interval [CI]=1.22-1.96), p<0.001). The logistic regression analysis for the genotype distribution resulted in strong association of risk allele C with MI under recessive model (OR=3.17 (95% CI=1.85-5.44) p<0.001). When the data were further analyzed along the lines of gender, a significant association with both males and females was observed. The pleiotropic role of rs1333049 was revealed further when CC genotype hypercholesterolemic individuals on statins were found to have a significantly lower TC, LDL-C and Tg levels as compared to the CG and GG individuals (p<0.05). The current study demonstrates a strong association of the ANRIL SNP (rs1333049) with MI as well as familial hypercholesterolemia patients in a northern Pakistani population and could be used as a useful genetic marker for the screening of MI in the general Pakistani population.
