If I’m found to be a ‘carrier’ after this testing, what does that actually mean for me and future pregnancies?

[Sana Fathima K S]

Being a carrier of a chromosomal change (like a balanced translocation or a small deletion) usually means the rearranged material is present in your cells but doesn’t cause health problems for you personally, many carriers are completely healthy and only discover their status after having an affected child.
The relevance is mainly for reproductive planning: carriers can have an increased chance of passing on an unbalanced version of the change to future pregnancies, which is why genetic counseling matters here. Your geneticist can walk you through your specific numbers and options, including preimplantation or prenatal testing for future pregnancies, once your own results are finalized. This is exactly the kind of question worth bringing directly to your genetics team, since the implications depend on the precise type and location of the change.
