项目摘要
The development of glioblastoma (GBM) has been hypothesized to be associated with relatively common
germline alterations with limited penetrance. Recently, two genome-wide association studies (GWAS) using
various single nucleotide polymorphism (SNP) array platforms have been performed in gliomas.
Collaborating with the group at the University of California at San Francisco (UCSF) we recently reported
that SNPs mapping near CDKN2A/B/ARF (9p21) and RTEL1 (20q13) are associated with the development
of high grade astrocytomas. In a separate study of patients with gliomas, MD Anderson and European
groups observed these associations as well as associations near TERT (5p15) and CCDC26/MLZE (8q24).
A re-analysis of UCSF/Mayo data suggests that the RTEL1 (20q13), TERT (5p15) and CCDC26/MLZE
(8q24) associations are largely restricted to patients with GBM, anaplastic astrocytoma and with
oligodendroglioma, respectively - suggesting that different germline polymorphisms are associated with the
development of different glioma subtypes. In this grant application we propose to further validate the
germline alteration(s) within and/or near to the CDKN2A/B (9p21), TERT (5p15), RTEL1 (20q13) and
CCDC26/MLZE (8q24) regions that are associated with the development of glioma, to correlate alteration
status with somatic genetic and expression alterations, with pathologic variables and with clinical
parameters. Our Specific Aims are: Aim 1: Perform detailed germline genetic analysis of the associated
CDKN2A/B (9p21), TERT (5p15), RTEL1 (20q13) and CCDC26/MLZE (8q24) regions using three cohorts of
prospectively glioma cases and controls to estimate the prevalence and relative risk of known
polymorphisms and new alterations. Aim 2: Evaluate the clinical, histopathologic, and molecular pathologic
relevance of the germline CDKN2A/B (9p21), TERT (5p15), RTEL1 (20q13) and CCDC26/MLZE (8q24)
alterations. This application is designed to validate the alterations in each of the four regions associated with
glioma development. Importantly, It will evaluate the clinical, pathologic and molecular pathologic relevance
of these alterations.
胶质母细胞瘤(GBM)的发展被假设与相对常见的
生殖系改变,具有有限的遗传变异。最近,两项全基因组关联研究(GWAS)使用
已经在神经胶质瘤中进行了各种单核苷酸多态性(SNP)阵列平台。
最近,我们与加州大学弗朗西斯科分校(UCSF)的研究小组合作,
CDKN 2A/B/ARF(9 p21)和RTEL 1(20 q13)附近的SNPs与
高级别星形细胞瘤在另一项神经胶质瘤患者的研究中,MD安德森和欧洲神经胶质瘤研究人员发现,
研究组观察到这些关联以及在TERT(5 p15)和CCDC 26/MLZE(8 q24)附近的关联。
对UCSF/马约数据的重新分析表明,RTEL 1(20 q13)、TERT(5 p15)和CCDC 26/MLZE
(8 q24)关联主要限于GBM、间变性星形细胞瘤和
少突胶质细胞瘤-这表明不同的生殖系多态性与少突胶质细胞瘤相关。
