Abstract

Ovarian carcinoma is the highest death cause in gynecologic malignancies. Although the molecular basis for familial breast and ovarian cancer is elucidated, few genetic markers have been associated with sporadic ovarian carcinoma. A polymorphism in intron G of the human progesterone receptor (PgR), caused by an Alu insertion, was described to be associated with ovarian carcinoma 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 receptor, 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 Austrian patients with sporadic ovarian carcinoma and a control group with 194 healthy volunteers for the PROGINS complex. The PROGINS status was studied in association with risk for ovarian carcinoma, the age of the ovarian patients, the protein level of PgR and estrogen receptor (ER) and histopathological parameters. The results indicate that the frequency of PROGINS carriers in 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 associated with increased risk for ovarian carcinomas. Additionally, the protein levels of ER and PgR were independent of the PROGINS status.
