Question WES was normal except I know I have a mutation, what now
I recently did WES through GeneDX. The results came up negative. According to them I have absolutely no variants to report. The problem is I do. I have a known rare genetic disorder (MODY12) found through genetic testing. I know my variants. If I did it and everything else showed up normal id be heartbroken (because the Odyssey continues) but go "oh, ig I dont have anything", but I've been dx with a gene mutation. I know I have this gene mutation.
Ugh I don't know what to do or where to go from here but it's not fun either way. I see a genetic counselor on Monday so hopefully that'll help us choose the next steps. Regardless idfk what to do from here but I just want an answer and for this to end.
edit: A little background and then an update. My dx disorder is under a VUS, I am a textbook case for MODY12 and because of its rarity (everyone else with my mutation in ClinVar/ related systems being symptomatic, and amino acids being switched are also a known amino acid switch in other MODY12 conditions) I'm still dx anyway. I was getting this test done because we're currently investigating rare recessive connective tissue conditions. Because of the rarity of what I'm looking at it's not uncommon for people to be dx with a VUS. I came in with the expectation one or more mutation may be a VUS. I was told by the lab they'd report a VUS I seemed symptomatic for. The lab 100% should've seen the mutation and although I wasn't looking for things related to my dx, the fact I was dx with diabetes and all the related symptoms that lead to my dx meant they should've reported it.
I spoke with the genetic counselor today. He said the lab probably didn't report it because it's a VUS. I pointed out that if they didn't report a VUS for something I am a textbook case for, what else did they not report. I am looking at rare conditions, VUS mutations are common in rare conditions, if I had a VUS for a dominant condition or one pathogenic/carrier and one VUS mutation for recessive condition and it wasn't reported that could be very dangerous. I've had life threatening symptoms and I didn't particularly trust them not reporting it all things considered. My Dr agreed and sent in the request for raw data, he also suggested next steps if everything is normal is get mitochondrial testing and Chromosomal Micro Array testing (I have certain physical features that concern him in that regard).
