In order to extend screening, more genetic variants in the J&K population, in-house cancer SNP panel was designed to screen the OC patients that comprises of eleven SNPs of ten genes (DNMT3A17, PIK3CA21,22, FGFR221,22, GSTP121,22, ERCC518–20, AKT116, CASC1615, CYP19A1, BCL215,23,24, ERCC125–30); and population based association study was conducted to assess the genetic predisposition of cancer susceptibility variants with OC. Here, CYP19A1 is linked to cancer.
