Delineation of a less than 200 kb minimal deleted region for cardiac malformations on chromosome 7p22

Abstract excerpt

Cardiac malformations are commonly seen in individuals with terminal and interstitial deletions involving chromosome band 7p22. Although these malformations represent a significant cause of morbidity, the dosage-sensitive gene(s) that underlie these defects have yet to be identified. In this report, we describe a 16-month-old male with tetralogy of Fallot, bilateral second branchial arch remnants, and mild...
