Fathers Can Pass Inherited Ovarian Cancer Risk to Daughters

Ovarian cancer risk is elevated in women with sisters or paternal grandmothers who have been affected, according to a study published in PLoS Genetics.

Kevin H Eng, PhD, of the Department of Biostatistics and Bioinformatics at Roswell Park Cancer Institute in Buffalo, NY, and colleagues hypothesized that ovarian cancer may be X-linked and the associated genes may be passed from the paternal grandmother though the father's inherited genetic material.

The investigators conducted a series of tests using DNA from 186 women with ovarian cancer who were registered in the Familial Ovarian Cancer Registry at Roswell Park Cancer Institute via germline X-chromosome sequencing.

They reported an earlier age-of-onset in paternal grandmothers compared with maternal grandmothers (hazard ratio [HR], 1.59), though both were mutually exclusive from BRCA1 and BRCA2.

To confirm X-linked association, the researchers measured the correlation between prostate cancer in men and ovarian cancer in their mothers and daughters (odds ratio [OR], 2.34). Mothers who did not have ovarian cancer but had affected daughters had significantly more female than male offspring (OR, 1.96).

“We have presented evidence that there may exist an X-linked model of transmission of an ovarian cancer susceptibility gene,” the authors wrote.

“Future studies are warranted to confirm the identity and function of the X-linked gene that contributes to familiar transmission of ovarian cancer.”
