✦ Synopsis

Nonradioactive in situ hybridization with an ctsatellite DNA probe specific for chromosome 18 was performed on human interphase sperm nuclei to detect the frequency of sperm cells disomic for chromosome 18. A total of 16127 sperm heads from eight healthy donors, aged 23-57 years, was investigated, and a minimum of 2000 sperm nuclei per proband was analyzed. The disomy rate ranged from 0.25% to 0.5%, with an average of 0.36%. This frequency does not differ significantly from that determined for other chromosomes.

Two highly conserved forms of cellular retinoic acid binding protein (CRABP-I and CRABP-II) have been described, and one, CRABP-II, is highly expressed in human skin.

The chromosome region 5q22 harbouring the putative gene associated with adenomatous polyposis coli (APC) was microdissected and microcloned from GTG-banded human metaphase chromosomes. In order to determine the precise regional localization of the microdissected material, we used polymerase chain re
