Abstract:
OBJECTIVETo perform genetic analysis of a complex chromosome rearrangement (CCR) 46,XY, t(3;11)(q27; q13), ins(11;3)(q13;p26p13) in an azoospermic man.
METHODSPeripheral blood lymphocytes we re obtained for karyotyping, and metaphases were studied by multicolor fluorescence in situ hybridization procedure, Y chromosomal microdeletions in the azoospermia factor (AZF) region were analyzed with multiplex polymerase chain reaction.
RESULTSThe case was a complex chromosomal translocation between chromosomes 3 and 11 with four breakpoints, and accompanied with a band of chromosome 3 inserting into chromosome 11. No Y-chromosome microdeletions were identified at 6 STS sequences of the AZF loci.
CONCLUSIONCCR can have a significant impact on male fertility. Molecular cytogenetic techniques may contribute to improving and personalizing reproductive counseling.
