RALD with somatic pathogenic variants ofNRAS andKRAS, CEDS, FADD deficiency,PI3κ,LRBA,CTLA4, GOF germlineSTAT3 mutations, and common variable immunodeficiency 9 (PRKCD deficiency) are considered ALPS-like disorders since they cause similar phenotypes, but the pathogenic gene variants may not be within the FAS/FASL pathway. Here, CTLA4 is linked to FADD-related immunodeficiency.
