EPCO-02. GERMLINE SINGLE NUCLEOTIDE POLYMORPHISM rs55705857 AT 8q24 INTERACTS WITH SOMATIC IDH1 MUTATION TO ENHANCE HUMAN GLIOMA FORMATION

ABSTRACT: Abstract

BACKGROUND

Determination of the causation of germline single nucleotide polymorphisms (SNPs) located in non-coding regions of the genome is challenging. The genomic region of 8q24 has been identified as important in many kinds of cancer, linked to a topologically associated domain (TAD) encompassing MYC; this TAD contains a GWAS SNP (rs55705857) associated with IDH-mutant glioma.

METHODS

Germline genotyping data from 622 IDH-mutant glioma and 668 controls were used to fine map the rs55705857 locus by detailed haplotype analysis. Chromatin immunoprecipitation sequencing (ChIP-seq) of histone markers H3K4me1, H3K4me3, H3K27ac and H3K36me3 was performed on normal brain samples (n=8) and human glioma samples (n=11 IDH-wt and 52 IDH-mut). RNAseq from 9 normal and 83 b
