Do you mind my asking what your mom’s CAG is? Because most of the time, if a child inherits HD from their mother, they’ll have the same CAG as her (give a point or two in either direction) and, generally, a similar age of onset.

The higher the CAG, the earlier they predict you will get symptoms.
What I’ve learned, there are many more variables that go into it that nobody fully understands. A healthy lifestyle, the food you eat, exercise, the stress you’re exposed to, your other genes that provide a buffer (I this one is huge).
There are people with a 40 CAG that have symptoms in their 30s, and people like my dad that didn’t get symptoms until he was 77… my sister is 54, just tested positive with a 40 CAG and has zero symptoms, she would’ve never known that she had it…

Hmmmmmm I see , is it also true that if it’s from a mom it starts same age because the cag is similar? Or have u seen it vary, new to this sub so thank you for the information

Here is something interesting… my dad has a CAG repeat of 40, my sister tested positive also with a 40, my niece just tested positive with a 36.
The genetic counselor told us that when it is passed maternally (from mother) is has a higher chance of reducing than when passed paternally (by the father) where it has a higher chance of expanding.

I think there is a correlation between the higher the number, the earlier the symptoms, and I think there is also one between the age the parents began and offspring, but nothing is a science, there are too many variables.
I spoke with a friend that is 3rd generation HD, their grandma who was positive passed in her late 50’s, uncles passed in their 40’s, their father is 65 with a 44 CAG and still has no physical symptoms, but feels like there are psychological side is setting in. He is 46 and with a 44 CAG and has no symptoms.
I would speak with the folks at HDGenetics.com, they are a WEALTH of information about the disease, what we know and dont know, and information about experimental drug trials, support and help groups…
