A 52-year-old woman who claims she was given the incorrect result for a breast cancer gene test eight years ago is now seriously ill with ovarian cancer, the High Court has heard.

The woman, a health care professional who lives in the Dublin area, found out in August this year she had late stage ovarian cancer and she is currently undergoing treatment but her prognosis is poor.

After developing and recovering from breast cancer in 2004, the woman later learned members of her family had a significant history of breast cancer and she had a genetic test in November 2009 for the BRCA 1 or BRCA 2 mutation gene, which is linked to breast cancer.

It is claimed the report from the testing laboratory showed a pathogenic change of the BRCA 1 gene, but in a letter sent to the woman and her treating doctor on 27 January 2010 it was incorrectly stated the breast cancer gene was normal.

The woman, whose youngest child is ten years old, has claimed she has suffered a loss of chance and the opportunity to take and seek medical advice to mitigate her risk of developing cancer.

She has further claimed if she had been made aware of the mutation and pathogenic change of the BRCA  1 gene in January 2010 she would have taken all steps necessary, including having a hysterectomy, to eliminate the possibility of cancer in the future.

The woman has brought an action against Our Lady's Childrens’ Hospital, Crumlin, Dublin which provides genetic testing at its Genetics Department, formerly knows as the National Centre for Medical Genetics, Cooley Road, Crumlin, Dublin.

In the High Court Senior Counsel Richard Kean said the woman is very seriously ill and the prognosis is very poor.

He said the case will take four or five days at trial and asked that it be specially fixed for a date in 2019.

Mr Justice Kevin Cross set 29 May next for the case to be heard.
