Thank you. I have an appointment with a nephrologist. I am concerned about the acidosis.

I have a lot of flank pain....which I thought was the result of disc disease, but, the last MRI, showed no discs out....hmm.

I AM going to see the renal doc, at an academic center, and also medical genetics.

I am diagnosed with Sjogren's, but do not have the +SSA or SSB....I am leaning toward a possible genetic cause of the dRTA. Have you had any genetic studies done? There is one European ethnicity, and only one, that shows a rare specific blood type associated with dRTA....and my ancestry is 50% from this group. I plan on having this tested. This blood marker is common in Mongolians, and it would have been the last place I would have looked for an abnormality, given my maternal side seemed very heterogenous....Heterogeniety apparently really doesn't matter when something is autosomal dominant.

I may be off on another wild goose chase, but, I am a detective of sorts....I want the RIGHT answer....no matter how long this takes. I want the correct diagnosis so my kids don't have to do this chase. If it is not hereditary...great....if it is, well, at least I found it.

Did you know dRTA comes with Sicca?

It is hard to know what is what with Sjogren's because it is cavalierly diagnosed....until all possibilities are ruled out....I will reserve judgment, and that is hard, because I so want to figure this out.

Again, thanks.
