      deletion   various size
      deletion   seven deletions ranging in size from 35 kb to 10.4 Mb, with the smallest deletion entirely within the SATB2 gene PMID 21343628
    Remark(s) cleft or high palate likely result of hemizygosity of SATB2 gene
    Genotype/Phenotype correlations deletion of 2q32 has been also associated with wrinkly skin syndrome (WWS)(Azuri 1999); ectodermal dysplasia-like syndrome including thin skin, oligodontia, dysplastic teeth, and sparse hair may be part of the del 2q32 syndrome (Rifai 2010);
