D. Tong et al., Analysis of the human progesterone receptor gene polymorphism progins in Austrian ovarian carcinoma patients, INT J CANC, 95(6), 2001, pp. 394-397
Ovarian carcinoma is the highest death cause in gynecologic malignancies. A
lthough the molecular basis for familial breast and ovarian cancer is eluci
dated, few genetic markers have been associated with sporadic ovarian carci
noma. A polymorphism in intron G of the human progesterone receptor (PgR),
caused by an Alu insertion, was described to be associated with ovarian car
cinoma in a pooled German/Irish population. Later on, a G to T substitution
in exon 4, causing a Valine to Leucine change in the hinge region of the r
eceptor, and a synonymous C to T substitution in exon 5 were reported to be
linked to the Alu insertion. This complex of the PgR gene polymorphism was
designated PROGINS. In order to investigate if PROGINS is associated with
risk for ovarian cancer in Austrian women, we analyzed DNA from 226 Austria
n patients with sporadic ovarian carcinoma and a control group with 194 hea
lthy volunteers for the PROGINS complex. The PROGINS status was studied in
association with risk for ovarian carcinoma, the age of the ovarian patient
s, the protein level of PgR and estrogen receptor (ER) and histopathologica
l parameters. The results indicate that the frequency of PROGINS carriers i
n Austrian women is similar to those in women in North America and England.
There is no significant difference between the PROGINS allele distribution
in ovarian carcinoma patients and healthy women. The PROGINS is not associ
ated with increased risk for ovarian carcinomas. Additionally, the protein
levels of ER and PgR were independent of the PROG INS status. (C) 2001 Wile
