QRSL1 and neuroblastoma: This finding is consistent with the significant overrepresentation of homozygous GATA/GATA genotypes in neuroblastoma revealed by GWAS in children, in that 57.9% of children with neuroblastoma had GATA/GATA, compared with 35.6% for GATA/TATA, and only 6.4% for the TATA/TATA genotype (20).
