PMID:39060684; 1x individual hom for Gly358Arg. 4x path in clinvar

PMID:29271561; 1x individual hom for c.882-2A>G. 5-year-old female who presented with features that mimicked autoimmune lymphoproliferative syndrome (ALPS) in the absence of classic features of DADA2

PMID:34721429; 2 sibs Chet for Leu188Phe and Thr187Pro and both had complete absence of inosine, an adenosine-derived product.
Leu188Phe is absent in gnomad v4 and clinvar. high conservation + 0.9 REVEL
Thr187Pro 1 het 0 homs in v4 and 1x clinvar citing this paper high conservation + 0.7 REVEL

PMID:30692987 ; 1x Chet Tyr456Cys and Trp399*. The missense 1x LP in clinvar by Invitae and 2 hets 0 homs in v4. high conservation + REVEL 0.7
