Inverted duplication 8p associated with deletion of the short arms of chromosome 8 (invdupdel[8p])is a relatively uncommon complex chromosomal rearrangement, with an estimated incidence of 1 in 10,000–30,000 live borns. The chromosomal rearrangement consists of a deletion of the telomeric region (8p23- pter) and an inverted duplication of the 8p11.2–p22 region. Clinical manifestations of this disorder include severe to moderate intellectual disability and characteristic facial features. In most cases, there are also CNS associated malformations and congenital heart defects. In this work, we present the cytogenetic and molecular characterization of seven children with invdupdel(8p) rearrangements. Subsequently, we have carried out genotype–phenotype correlations in these seven patients. The majority of our patients carry a similar deletion but different size of duplications; the latter probably explaining the phenotypic variability among them. We recommend that complete clinical evaluation and detailed chromosomal microarray studiesshould be undertaken, enabling appropriate genetic counseling.
