From our symposium - Scaling Omics Approaches to Population Size: the unedited talk of Jon Foss-Skiftesvik, Rigshospitalet and Statens Serum Institut. One of six young researchers selected from submitted abstracts to give a talk. On the topic: Genome-wide association study across pediatric central nervous system tumors implicates shared predisposition and points to 1q25.2 (PAPPA2) and 11p12 (LRRC4C) as novel candidate susceptibility loci.
