Genetic analysis of polymorphism rs10937405 of TP63 gene in breast and ovarian cancer patients of North Indian Cohort.

Introduction: Ovarian and breast cancers are highly prevalent in the population of Jammu and Kashmir (J&K). However, case–control association studies on breast and ovarian cancers are lacking in this population. Moreover, no case–control study is available on variant rs10937405 of TP63 in breast and ovarian cancers. Thus, we designed to replicate the cancer susceptible variant rs10937405 of TP63 in ovarian and breast cancers in the population of J&K because the TP63 gene act as a tumor suppressor gene and was previously associated with various cancers. Materials and Methods: This case–control association study conducted at the Shri Mata Vaishno Devi University, includes 150 breast, 150 ovarian cancer cases, and 210 healthy controls (age and sex‑matched). Variant rs10937405 of the TP63 gene was determined by the TaqMan assay. Hardy–Weinberg equilibrium for the variant was assessed using the Chi‑square test. The allele and genotype‑specific risks were estimated by odds ratios (ORs) with 95% confidence intervals (CI). Results: In this study, variant rs10937405 of TP63 gene did not show any risk with ovarian and breast cancer with (P‑value = 0.70) having OR 0.94, (0.69–1.28 at 95% CI) and (P‑value = 0.16) having OR 0.80, (0.59–1.10). Discussion: Our results indicate that the variant rs10937405 of the TP63 gene did not impart any risk of breast and ovarian cancer in the population of J&K. Our results indicate that a larger sample size is needed for further statistical validation. As the study was for a particular variant, it warrants the analysis of other variants of this gene.
