Human uterine leiomyomas, mostly cytogenetically characterized, were a
nalyzed by Southern blotting. The region 7q22.3-q31.2 was analyzed in
54 leiomyomas using the polymorphic probe D7S13. The region 14q22-24 w
as investigated in 25 leiomyomas with the probe HSPA2. No evidence of
rearrangement or amplification of these DNA-regions was observed. Nor
was any loss of polymorphism for the probe D7S13 seen. These, and earl
ier negative results, motivate further molecular investigation to unde
rstand the mechanisms reflected by recurrent chromosome aberrations in
myomas.
