Parental Dilemma

stories-single-blob

I suffer from a genetic condition known as Autosomal Dominant Polycystic Kidney Disease (ADPKD), in which cysts develop on the kidneys and other organs. The cysts multiply and grow, eventually destroying the kidneys. In common with a number of other people to whom I’ve spoken, I believed that the condition spread down the female line, but that isn’t the case. Every child of a parent with the defective gene has a 50/50 chance of inheriting the disease.

Our son was born five years before I was diagnosed, and whether or not my wife and I would have had any children knowing I had the condition before my son was born may be a subject for a future blog. The dilemma I want to focus on is whether you should have your child tested for a genetic condition. I spoke to an ADPKD sufferer last week who said they wouldn’t test their child, arguing that it is better not knowing.

As my son grew up, my wife and I regularly discussed the matter of having him tested, knowing that it would be his late teens at the earliest before an ultrasound scan would be able to confirm a diagnosis. We were never in any doubt that it was better to know than not know despite the problems that confirmation could bring, such as grossly inflated insurance premiums, a life on blood pressure medication and ultimately, renal failure. It transpired that he’d inherited the condition, and while I wrestled with my misplaced feelings of guilt for passing on the condition, we were thankful that he’d been diagnosed some 16 years younger than I was when I was diagnosed. The knowledge gave him an opportunity to adjust his lifestyle and have better blood pressure control in the hope that it may prolong kidney function.

So my question is, and it applies to any genetic disorder, would you test your child, or would ignorance be bliss?
