Our “miracle daughter” Bianca, who tested negative in the womb for Huntington’s disease in early 2000, recently turned 13. As my wife Regina and I have watched Bianca transform before our very eyes into a teenager, I have contemplated the beauty and fragility of this miracle of life. Bianca’s latest birthday was doubly special: she became a teenager, and we again quietly gave thanks for her gene-negative status.
Had Bianca tested positive for HD, she might now be facing the scourge ofjuvenile Huntington’s (JHD), a particularly cruel form of the disease caused when a gene-positive parent, usually the father, passes on a more severe form of the genetic mutation, causing onset to occur as early as the toddler years. JHD strikes while a person is still developing physically and neurologically.
JHD can cause considerable pain, and some patients require operations for problems such as deformed limbs. Few JHD patients survive beyond the age of 30, and some die during childhood.
Whenever I witness JHD families’ terrible struggles, I breathe a sigh of relief that we as a family avoided such an immense burden on top of my race against the genetic clock. Nobody’s exempt from life’s challenges However, as a father striving to provide Bianca with a safe, stable, and promising upbringing, I know that freedom from HD doesn’t mean freedom from life’s other risks. Regina and I must still help her negotiate not only the successes, but also the many challenges that lie ahead – and to know when to step back and let her handle them on her own.
We’re also aware that each day illnesses of all sorts, genetic and otherwise, strike many teens and young adults. The other day I learned that a friend’s son faces an incurable, though partially treatable genetic disorder. My heart sunk when I learned of the difficulties that await this young person.
The HD community faces many tribulations, but so many others suffer, too. Understanding this helps Regina and me to put our family’s situation in perspective. Genetics, families, and ethics Child-rearing provides the key to understanding a major human purpose: propagating the human species and aiming toward a brighter future. Today the study of genetics and the search for treatments for life-threatening genetic conditions such as HD constitute a new human purpose but also new, ever-more-nuanced definitions of conception and the family. Regina and I faced the terrible possibility of bearing a child with the HD gene.
In 1999, preimplantation genetic diagnosis (PGD) wasn’t possible. Today it helps families eliminate HD forever from the family line In the Genomic Era, families can take advantage of new scientific tools, but use of these tools also forces us to confront new ethical and moral questions.
Best strategy: honesty Regina, Bianca, and I rarely discuss HD as a family matter, but it does frequently come up in the context of my advocacy as a volunteer for theHuntington’s Disease Society of America (HDSA) and writer of this blog. In 2012 and 2013 the three of us took part in the local annual HDSA Hope Walk to raise funds and awareness.
