Zimmermann-Laband syndrome (ZLS) is a rare autosomal dominant disorder, the genetic basis of which has not been identified thus far. We previously mapped the breakpoints of two different translocations in patients with ZLS to a common region in 3p14.3; however, we failed to detect mutations in genes located in a region surrounding both breakpoints as well as in those of another breakpoint region (8q24.3) (Abo-Dalo et al., 2007). The WNT5A gene is located proximal to both breakpoints in 3p14.3, with a distance of around 550 kb or less, making it likely that a position effect may cause deregulated expression of WNT5A. This gene codes for a secreted glycoprotein that belongs to a family of sign..
