Are there any genetic counselors in this group?

We are planning baby #3

My husband has polydactyly, Our 1st son dif not get it, but our 2nd son did get it.

My husbands dad has it, he passed it on to his two sons but his two daughters did not get it.

My husbands granfather was the 1st in the family to have it that I know of, He passed it on to his son and his two daughters.

One of his daughters didnt pass it on to her daughter but her son had it. The other daughter has a son but he didnt get it either.

My question is: How likely is it that our 3rd child to get it? Also, it seems to not show up as much in girls, is that just likely? Would our odds be same no matter what the gender is?

My last question is the defect has shown in so many different variations and ways, is it likely that it could be worse than how my husband has it? Any other information would be greatly appreciated, our son is having to go through atleast 6 surgerys as he has both hands and both feet & we are scared for our next child.

I’d recommend going to a genetic counselor for real to get these questions answered. You don’t know if someone on this app is lying and people deserve to be compensated for their work/expertise.

A quick Google search will tell you that polydactyly is 2x as common in men as it is in women and that it’s a dominant gene when inherited. Assuming your husband has one copy of the dominant causing polydactyly and one recessive “normal” copy, your chances are 50-50 with each child that they will or won’t have it.That said, seeing a genetic counselor is going to give you a lot more info and be much more specific to your family and they can present you with more options. The good side of polydactyly, as far as birth defects go, is that it’s mostly just aesthetic, when it’s an isolated finding. Baby can go on to live a perfectly normal life, though I know surgery of any kind is not easy for child or parent. It’s really too complex a situation to be answered in a post, fully. Best left to the pros.
