What should rheumatologists know about ‘somatic mutation’? 12:31
Do you think this could be a clue to other conditions? 13:37
Can you tell us about some of the unique aspects that we see in these patients with MDS that make them atypical? 17:14
How’s the clinician going to see or note the vacuoles? 18:53
Do we have kind of a pathway for how the vacuoles are forming based on what we know about ubiquitization or is that unclear? 20:51
What’s going to raise the antenna that this isn’t “run of the mill x disease”? 23:33
How, in your experience, have patients responded to diagnoses being changed? 37:15
Where does everyone see the therapy going for this condition in the future? 41:15
Do we think that with this approach that this is going to “reshuffle the deck” of what we call certain diseases from multiple different specialties over the next decade? 44:02
Would you mind walking us through a little bit about FMF and how the different variants you saw led to further discoveries? 49:46
What was known about IL1 at the time? How did that knowledge of IL1 come along? 52:53
It’s such a true honor to have you all on 57:42
