Abstract
We report a 10-year-old Caucasian male identified with copy number variation detected by microarray analysis including a maternally inherited 15q11.2 microdeletion involving 4 genes, paternally inherited 13q12.2 microdeletion with 10 genes, and a de novo 2q14.3 duplication involving four genes. He had a history of speech delay, cognitive deficits, attention deficit hyperactivity disorder and a posterior lenticonus cataract removed at 5 yr of age. The genes on chromosomes 2 and 13 are not known to be involved with cataract formation, which lends further support for a role of the 15q11.2 region and additional evidence for phenotypic expansion of the 15q11.2 BP1-BP2 microdeletion (termed Burnside-Butler) syndrome.
Keywords: Microarray analysis, motor and language delay, congenital cataracts, dysmorphic features
