I thank the Minister, Deputy Taylor, for attending this evening. Ireland is a leading country in the human genome project, that is, the identification of all human genes. Some of the most important recent developments in medicine have been in the field of genetics. These advances have been exciting but they have also been a cause of anxiety for some people.
The diagnosis of diseases due to faulty genes is far ahead of the possible cure or amelioration of many of these conditions. Some people now know of their genetic predisposition to a disease but not whether this disease will become manifest. There are many diseases where lifestyle and environmental factors can be as important as genetic predisposition. However, there are social and psychological factors which are influenced by the knowledge of the faulty genes.
It is enough for a healthy person to find the presence of an abnormal gene without the additional worry that this could be held against him in employment or any other area. The Department of Equality and Law Reform is bringing forward additional legislation regarding equality in employment on foot of a European directive and I hope this legislation will go further than the directive. I recently pointed out during the discussion of another Bill that the Minister has often gone further than EU directives in the legislation he presents. I hope this legislation will outlaw discrimination on the basis that an apparently healthy person had an abnormal gene.
This type of legislation is under consideration or has been enacted in other European countries. The US Equal Employment Opportunities Commission has barred gene discrimination under the Americans with Disability Act earlier this year. This is the first federal document to declare it illegal for an employer to discriminate against a worker on his or her genetic make-up.
Such legislation is needed here. While it is important from a civil rights aspect it is also important from a medical perspective. In the past none of us knew our genetic make-up. It is now known that certain conditions — some serious, some less so — run in certain families. In some circumstances the disease may develop inevitably but in others this is not the case. It may be possible for a person with a genetic tendency to a certain disease to so modify their behaviour that the disease will not develop.
If a person has a genetic predisposition towards hypercholesteralaemia, that is having high fat levels which can cause heart disease, it could be valuable for them to know this early in their lives so that they might find a suitable diet, exercise more and refrain from smoking. Indeed, they could do all the things we should all do.
Many patients would be reluctant to undergo such tests if they felt the results could be used against them later. Medical and lifestyle changes could prevent or delay the onset of cardiac diseases in the cases I have mentioned. There are other conditions where a change in lifestyle or a modification of environment could be important.
The US Equal Employment Opportunities Commission acted because some employers in the US were insisting on employees taking genetic tests if it came to their notice that a member of the family had an hereditary condition. I read of one serious case where an employer found out the mother of a girl he employed had Huntingdon's chorea. This is a serious neurological condition with mental and physical problems, which, however, do not usually develop until a person reaches the fourth decade of life.
The girl was forced by her employer on threat of dismissal to have a gene test to see if she carried the gene. Given this is an inevitable condition this was extremely serious. About 50 per cent of the children of sufferers of Huntingdon's chorea will develop it. Tragically, when this girl took the test she found she had the gene and would develop the condition. This knowledge destroyed her life totally. She might not have known her fate for another 20 years but she was forced into this knowledge due to having to take the test.
Fortunately, with most conditions a genetic defect need only predispose a person to having a disease. These conditions apply to almost everyone: almost all of us could say we have an abnormal gene, but it may never affect us in later life. We could all be classified as "genetically disabled" but we should not be classified as "disabled" until a particular condition develops.
There are serious social and ethical issues involved in mapping genes and using information so acquired. Genetic records should be kept private and should not be used for employment, insurance or any other discrimination, but should only be used in a manner helpful to the individual involved or their family.
We must go forward on this topic to avoid people feeling genetically stigmatised. The science of eugenics has a dubious and unpleasant background. The real science of genetics should have a bright and hopeful future for mankind.
