A question asked by fffan215: If someone is a dormant carrier of cystic fibrosis, what are there symptoms (if any) and how is it passed on?My sister found out she has cystic fibrosis today. she said that she found out she has a portion of it and if her boyfriend has it too then there soon to be baby may have it. she wont stop crying and I want to know if this is that serious… and since she only has a dormant portion of the disease and its genetic.. if her or I could be affected by it’s symptoms. Thanks for your help I truely appreciate it.
Chosen answer:
Answer by KBYou and she won’t have symptoms. she just has the recessive gene for it and so does her boyfriend. The only way their child will get it is is they both end up giving her the recessive gene for it.
The child gets a gene from each parent for everything. In order to have this disease, you must have two recessive genes (the CF gene from each parent). If you only get one recessive gene from one parent and one normal gene from the other parent, you still won’t have it. You will just be a carrier of the gene like your sister. or the child could get a dominant normal gene from each parent and then not be a carrier and not have the disease (best case scenario).
Basically, in perfect genetics, their baby has a 25% chance of getting CF, a 50% chance of being a carrier, and 25% chance of being completely free of the gene. The odds are the baby will not have CF itself but there is still that chance.
I wish her luck.
