title: Interstitial deletion of the band 4p15.3 defined by sequential replication banding.
abstract: A 15-year-old boy with intellectual disability was found to have a de novo interstitial deletion in the short arm of chromosome 4. Using GTL banding and sequential replication banding the deleted band was found to be the more terminal of the two G dark sub-bands of 4p15, that is 4p15.3. The karyotype was defined as 46,XY,del(4)(p15.2p16.100). To our knowledge this specific deletion has not been previously described.
