Fig. 2From: A case of germline mosaicism for a 7q32.1q33 deletion in a sperm donor: consequences on pregnancy follow-up and recommendationsIdentification of the germline mosaicism by fluorescent in situ hybridization analysis of the spermatozoa of the sperm donor. After sperm head decondensation, a locus specific probe at locus 7q32.3 (in red) and chromosome 7 control probe (in green) were co-hybridized. Sperm DNA was counterstained with DAPI (4′,6-diamidino-2-phenylindole). The arrows indicate the sperm heads carrying the deletion (one spot for the control probe and no spots for the specific probe)Back to article page
