Investigation of the co-occurrence of panic and phobic disorders with joint laxity led to the identification of various forms of interstitial duplications involving human chromosome 15q24-q26 (named “DUP25”) in a Spanish population. DUP25 was observed in 68 of 70 (97%) patients assigned the diagnosis panic disorder/agoraphobia. DUP25 was also found in 14 of 189 (7%) control individuals. In the present study, we replicated the experimental conditions described by Grataco` s and colleagues in which fluorescence in situ hybridization was used to examine metaphase chromosomes of patients with panic disorder/social phobia and of control individuals from a southern region of the United Kingdom, the primary aim being to determine the prevalence of this chromosomal rearrangement in a geographically and ethnically distinct population. DUP25 was not observed in any of our 16 patients or 40 control samples or in three previously reported DUP25-positive control (Centre d’Etude du Polymorphisme Humain) cell lines, indicating a highly significant difference in the frequency of DUP25 between the study by Grataco’s and colleagues and the present investigation.
