Identification of the origin of marker chromosome by comparative genomic hybridization / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To identify the origin of the marker chromosome in a patient with chromosome aberration, and to provide the precise genetic diagnosis.@*METHODS@#Comparative genomic hybridization (CGH) and fluorescence in situ hybridization (FISH) were performed to detect the known small marker chromosome in this patient.@*RESULTS@#The small marker chromosome originated from chromosome 13 pter->q12.@*CONCLUSION@#CGH and FISH can be used to detect the small marker chromosome, which is convenient and quick in detecting the origin of small marker chromosome.
