Aim of study
The aim of the study was to investigate the role of individual susceptibility factors on the aetiology of brain tumours. The study was a part of the INTERPHONE study.
Implementation
In this study we examined the possible associations between genotypes of different gene polymorphisms and the risk of primary adult brain tumours (glioma, glioblastoma or meningioma). The study was conducted as an international collaboration forming a part of the INTERPHONE study so that genotypes of the DNA-repair genes XRCC1 and XRCC3 were studied at STUK. We genotyped DNA collected for an international population-based case-control study of 725 glioma cases (containing 329 glioblastoma cases), 546 meningioma cases and 1612 controls. Study participants were residents of Denmark, Finland, Sweden, and southeast England. Genotypes of xenobiotic metabolism, DNA-damage repair, apoptosis and folate metabolism genes were genotyped in three other laboratories using these same DNA samples.
Polymorphisms of xenobiotic metabolism genes were found not to be associated with the risk of brain tumours (1). Polymorphims of important DNA-damage repair genes (p53 and ATM) were shown to both increase and decrease the risk of brain tumours depending on the combination of the inherited genotypes (2).
The combination of the rare variants of the DNA-repair genes XRCC1 and XRCC3 indicated possible increase in the risk of glioma and meningioma (3). When 1459 polymorphisms in the DNA-damage repair genes were studied, it was shown that glioma risk was increased most prominently in association with a certain polymorphism at the CHAF1-gene (4). Polymorphism at the BRIP1-gene was consistently associated with an increased risk of developing meningioma (5).
A rare variant of the apoptosis gene CASP8 was shown to increase the glioma risk (6). However, the same variant was not associated with a statistically significantly increased risk of meningioma (7). Variant genotypes of folate metabolism genes MTHFR and MTRR were associated with increased risk of both glioma and meningioma (8).
