This study genotyped the single nucleotide polymorphism (SNP) rs78378222 in 566 glioma cases and 603 controls. The variant ā€˜Cā€™ allele (with an allelic frequency of 1.1% in controls) was associated with a 3.5-fold excess in glioma risk (odds ratio 3.54; p=0.0001). Variant carriers had significantly improved survival (hazard ratio 0.52; p=0.009) when compared to non-carriers. The rs78378222 SNP is the first confirmed rare susceptibility variant in glioma. Results may shed light on the aetiology and progression of these tumours.
