Association of HOTAIR rs7958904 Polymorphism with Cervical Cancer Risk

Cervical cancer (CC) has been the prominent cause of cancer-associated fatalities among women in developing countries. In terms of occurrence and mortality, it is ranked second in Bangladesh. Although different genetic polymorphisms linked with this cancer have been investigated over time, the association between the HOTAIR rs7958904 variant and cervical cancer is being reported for the first time in Bangladeshi women. RT-PCR-based TaqMan assay was employed to perform this case-control study on 200 cervical cancer patients and 148 healthy volunteers. Both cases and controls had average ages of 57.5 and 52.5 years, respectively. According to Hardy-Weinberg equilibrium, the rs7958904 allele of HOTAIR gene pretended no deviation for both cases and control groups. The genotyping results showed that rs7958904 has a significant correlation to the development of cervical cancer in different genetic association models, such as co-dominant 1 (CC vs. GG: OR = 1.67, p = 0.0435), co-dominant 2 (CC vs. GG: OR = 3.13, p = 0.0006), co-dominant 3 (CC vs. CG: OR = 1.88, p = 0.0384), dominant (CG + CC vs. GG: OR = 1.98, p = 0.004), recessive (CC vs. GG + CG: OR = 2.25, p = 0.005), and allele model (C vs. G: OR = 1.70, p = 0.0006). In conclusion, the HOTAIR rs7958904 variant has a substantial role in cervical cancer development in Bangladeshi women. Further functional studies with a larger population size are required to support our findings.
