Replication of MACF1 gene variant rs2296172 with type 2 diabetes susceptibility in the Bania population group of Punjab, India
2018
Microtubule actin cross-linking factor 1 (MACF1) gene variant rs2296172 has recently been associated with type 2 diabetes (T2D). However, this variant has never been evaluated as such in Indian populations. In the present replication study, we genotyped variant rs2296172 by Taqman allele discrimination assay in 432 individuals belonging to the Bania caste group from Punjab, India. The single-nucleotide polymorphism (SNP) was evaluated for association with T2D, in a population based candidate gene case-control association study design, by estimating odds ratio with 95% confidence interval. The SNP rs2296172 of MACF1 was found to be significantly associated with T2D (p = 0.02) and odds ratio (OR) = 1.59 (1.06–2.38) at 95% CI . We further emphasize that the Indian population as such is a conglomeration of various endogamous population groups. It is critical that such replication studies be carried out in various populations to find association of variants to T2D susceptibility and understand genetic heterogeneity. However, it is important to avoid pooling of samples to address the concern of population stratification.
