Clinical phenotypes and location of copy number variation in a family with 15q13.3 duplication, including the unaffected mother (UM), affected proband (AP), and his affected brother. Note that the minor differences in reported lengths of the duplications between subjects reflect the limits of resolution of detection by chromosomal microarray analysis
