ABSTRACT
We describe a de novo partial duplication of 7p in a 25-year-old male with autistic disorder (AD). High-resolution chromosome analysis revealed an extra segment added to the proximal short arm of chromosome 7. The G-band pattern was consistent with an inverted duplication of 7p11.2-p14.1. Fluorescent in situ hybridization (FISH), using a whole chromosome 7 DNA probe (Cytocell, Inc., UK), confirmed that the extra chromosome material is derived from chromosome 7, indicating that the patient is partially trisomic for a region of the short arm of chromosome 7. Partial duplication of the short arm of chromosome 7 is uncommon with little more than 30 cases in the literature. This is the first report of an individual with a 7p duplication who also has AD.
