Objective:
To assess the value of fluorescence in situ hybridization (FISH) and bacterial artificial chromosome FISH (BAC-FISH) for the diagnosis for patients with marker chromosomes.
Methods:
Sixteen patients with marker chromosomes were analyzed with technologies including GTG-banding, Q-banding, multiplex FISH and BAC-FISH.
Results:
The marker chromosomes in the 16 patients were verified as der(Y) (2 cases), psu dic(Y) (1 case), psu dic(15) (1 case), dic(15) (1 case), del(Y) (1 case), r(X) (5 cases), i(14 or 22) (2 cases), i(18) (1 case).
Conclusion:
FISH and BAC-FISH can both verify the origin of marker chromosomes and provide accurate information for the diagnosis and treatment of patients.
