KDR and glioma: A previous study identified an close relationship between rs2305948 and coronary heart disease.[30] In addition, a close relationship between rs2305948 and myocardial infarction in Caucasians has also been identified.[31] Another study documented a close association between susceptibility to stroke and rs2305948.[32] Many case-control studies on the relationship between the VEGFR2 polymorphism rs2305948 and glioma risk have been conducted, but the conclusions have not been consistent.
