Huntington’s disease isn’t a condition that one simply stumbles upon. Instead, it’s inherited, traveling through the bloodlines from parent to child.
This disease is passed down in what’s known as an ‘autosomal dominant’ manner. In simple terms, this means that an affected person has a 50% chance of passing on the faulty gene to their offspring. It’s a coin toss with profound implications.
Interestingly, you don’t need to inherit two copies of the faulty gene (one from each parent) to develop the disease, as is the case with some genetic conditions. Here, inheriting just one copy is sufficient to set the wheels of the disease in motion. It’s a testament to the power and influence of this single gene mutation.
If a parent has Huntington’s disease, every child they have stands a 50% chance of inheriting the disease. It’s an unshakeable reality that adds a layer of complexity and emotional struggle to family planning decisions for those affected by Huntington’s disease.
This autosomal dominant pattern of inheritance underscores the importance of genetic testing and counseling in families with a history of the disease, not just for potential carriers but also for their potential offspring. While knowing one carries the mutation doesn’t change the disease’s inevitability, it can inform important life decisions and facilitate early intervention strategies. (2)
