Molecular genetics of adult ADHD: converging evidence from genome-wide association and extended pedigree linkage studies


Lesch, K P; Timmesfeld, N; Renner, T J; Halperin, R; Röser, C; Nguyen, T T; Craig, D W; Romanos, J; Heine, M; Meyer, J; Freitag, C; Warnke, A; Romanos, M; Schäfer, H; Walitza, S; Reif, A; Stephan, D A; Jacob, C (2008). Molecular genetics of adult ADHD: converging evidence from genome-wide association and extended pedigree linkage studies. Journal of Neural Transmission, 115(11):1573-1585.

Abstract

A genome-wide association (GWA) study with pooled DNA in adult attention-deficit/hyperactivity disorder (ADHD) employing ~500K SNP markers identifies novel risk genes and reveals remarkable overlap with findings from recent GWA scans in substance use disorders. Comparison with results from our previously reported high-resolution linkage scan in extended pedigrees confirms several chromosomal loci, including 16q23.1-24.3 which also reached genome-wide significance in a recent meta-analysis of seven linkage studies (Zhou et al. in Am J Med Genet Part B, 2008). The findings provide additional support for a common effect of genes coding for cell adhesion molecules (e.g., CDH13, ASTN2) and regulators of synaptic plasticity (e.g., CTNNA2, KALRN) despite the complex multifactorial etiologies of adult ADHD and addiction vulnerability.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
