Abstract

We conducted a genome-wide association study to search for risk alleles associated with Tetralogy of Fallot (TOF), using a northern European discovery set of 835 cases and 5159 controls. A region on chromosome 12q24 was associated (P 1.4 10(7)) and replicated convincingly (P 3.9 10(5)) in 798 cases and 2931 controls [per allele odds ratio (OR) 1.27 in replication cohort, P 7.7 10(11) in combined populations]. Single nucleotide polymorphisms in the glypican 5 gene on chromosome 13q32 were also associated (P 1.7 10(7)) and replicated convincingly (P 1.2 10(5)) in 789 cases and 2927 controls (per allele OR 1.31 in replication cohort, P 3.03 10(11) in combined populations). Four additional regions on chromosomes 10, 15 and 16 showed suggestive association accompanied by nominal replication. This study, the first genome-wide association study of a congenital heart malformation phenotype, provides evidence that common genetic variation influences the risk of TOF.
