ABSTRACT
Objective To explore the relationship between the fibroblast growth factor 2 (FGFR2) gene polymorphism (rs 2981582 ,rs 1219648 ,rs 2420946) and the breast cancer risk in Tibetan population ,Qinghai province .Methods This is a case con‐trol study .Peripheral blood samples from 210 breast cancer patients and 230 healthy women in Qinghai area were collected .DNA samples were extracted from peripheral blood cells .FGFR2 gene polymorphism (rs 2981582 ,rs 1219648 ,rs 2420946) were typed by Taqman‐MGB probe based on PCR and DNA sequencing ,then analyzed its correlation with breast cancer in Tibetan population , Qinghai province .Results The genotype frequencies of rs 2981582 CC ,CT and TT were 40 .48% ,39 .05% and 20 .47% among the breast cancer patients while 36 .09% ,48 .69% and 15 .22% among the controls .The genotype frequencies of rs 1219648 GG ,AG and AA were 24 .76% ,26 .19 % and 49 .05% among the patients while 23 .91% ,47 .39% and 28 .70% among the controls .The genotype frequencies of rs 2420946 CC ,CT and TT were 29 .05% ,45 .24% and 25 .71% among the patients while 30 .87% , 51 .74% and 17 .39% among the controls .The genotype frequencies of all genetic loci had no significant difference between rs 2981582 and rs 2420946 (P>0 .05) .But the genotype frequencies of rs 1219648 AA have statistical sense (P< 0 .05) ,compared with GG ,the incidence of breast cancer was remarkably increased with AA [OR=1 .65 ,95% CI= (1 .01 ,2 .69)] .Conclusion This study shows that FGFR2 rs1219648 AA is related to breast cancer risk among Tibetan population .
