Abstract
Complex chromosomal rearrangement (CCR) is a structural abnormality of chromosomes that rarely appears in individuals with normal phenotypes. A CCR involving chromosomes 9, 13, and 22 was ascertained in a phenotypically normal woman through a neonate with multiple congenital malformations and partial trisomies of 13 and 22. We diagnosed the CCR using high-resolution chromosome analysis and three-color fluorescence in situ hybridization (three-color FISH) analysis, and ascertained a balanced CCR without cryptic imbalances using array comparative genomic hybridization (array CGH) and FISH. In the present work, we report on the case together with a literature review.
