Question

The first signs of Huntington’s disease often appear when a person is in his or her 30s and 40s, but it can appear later in life. The earliest symptoms are often subtle, such as mood changes. Do you think the subtle presence of symptoms plays a role in this harmful gene persisting in our population? Why or why not?

Answer 1

Yes, subtle presence of symptoms contributes to persistence of the gene. People may not know they have the condition before having children, especially if an affected parent does not have clear signs or symptoms of the disease yet. It could also be a problem if the expecting parents do not know their birth parents or their medical histories.

Answer 2

Yes, these symptoms might be useful for the identification of aberrant expression patterns of the gene involved in Huntington disease

Step-by-step explanation:

Huntington is a genetic dominant disorder associated with the mutation in the huntingtin (HTT) gene. The HTT gene encodes for a protein whose mutant form might be toxic when expressed at high levels
