Mosaic Ring Chromosome 18, Ring Chromosome 18 Duplication/Deletion and Disomy 18: Perinatal Findings and Molecular Cytogenetic Characterization by Fluorescence In Situ Hybridization and Array Comparative Genomic Hybridization

Abstract

Array comparative genomic hybridization is useful to determine the breakpoints of a ring chromosome, particularly in cases where the ring chromosome comprises the majority of the mosaicism.
