title: Case report: cytogenetic and molecular analysis of proximal interstitial deletion of 4p, review of the literature and comparison with wolf-hirschhorn syndrome.
abstract: We report on a two-year-old female with a de novo proximal interstitial deletion of the short arm of chromosome 4 and a tetralogy of Fallot malformation. The patient had a karyotype of 46,XX,del(4)(p14p15.33) that was further characterized by array comparative genomic hybridization (aCGH). Phenotypic abnormalities for our patient are compared with those of previously reported patients with similar proximal 4p deletions as well as more distal deletions. The functions of genes that are deleted within this segment are reviewed.
