@TypeZero. - this is something you need to discuss with your Endo Team. If your antibodies are in an undesirable place, you may be offered a colonoscopy to rule Coeliac in or out, at that point.
Autoimmune conditions do tend to hunt in packs (as I see it in my little brain), but just because someone in your family has such a condition doesn't mean you do too.
My family history is littered with AI conditions from Diabetes (of all types, 1, 2 and 3c), hyperthyroidism/Graves, rheumatoid arthritis, fibrosing alveolitis, psoriasis and so on. My parents alone accounted for 5 of those listed - mother 2, father 3. I have none. Zero. I'm happy with that.
I have just gone through another round of testing for RA, with a referral to Rheumatology in process, due to painful, inflamed joints - without any of the usual markers.
All I will say is AI conditions can be sneaky, as confirmed by my Endo who has a wager I
eventually turn out to be LADA. For now, 7 years in, with serial A1cs in the 30s, I'm quite happy to see him eating his hat every few months, when he enquires.
See your team. They're the only ones who can help map out a way forward.
