Abstract

Several groups have reported association between large CAG/CTG repeat sequences in the genome and bipolar disorder using the Repeat Expansion Detection (RED) method. Unfortunately, the RED method cannot identify the specific repeat(s) responsible for these findings but it has recently been proposed that around 90% of the large CAG/CTG repeats detected by RED can be explained by repeat size at either CTG18.1, which maps to 18q21.1, or ERDA-1 (also known as Dir 1), which maps to 17q21.3. These data suggest that the previous associations between bipolar disorder and large CAG/CTG repeats might be explained at least in part by a specific association between bipolar disorder and either or both of these loci. However, using a case control study design, we find no evidence for such associations. Thus we conclude that in our sample, the previous RED associations are not a result of large CAG/CTG repeats at CTG18.1 or ERDA-1. Copyright 1999 Academic Press.
