Heterozygous mice (the same frizzled 9 genotype as Williams syndrome patients) were intermediate between wild type and null mice for all developmental neuronanatomic defects.

A cognitive phenotypic map of WMS is presented, which combines previous data with five further WMS subjects and three atypical WMS subjects with deletions; two larger (deleted for D7S489L) and one smaller, deleted for genes telomeric to FZD9, through LIMK1, but not WSCR1 or telomeric.
We previously identified a novel frizzled gene, FZD3, now renamed FZD9, in the Williams-Beuren syndrome (WBS) deletion region at chromosomal band 7q11.23 and showed that its product can interact with the Drosophila wingless protein.
