Immunodeficiency, developmental delay, and hypohomocysteinemia (IMDDHH)

Disease ID:1264
Name:Immunodeficiency, developmental delay, and hypohomocysteinemia (IMDDHH)
Associated with:1 target
1 immuno-relevant target
Description
IMDDHH is a early onset multisystem disorder that is characterised by immunodeficiency, recurrent infections, developmental delay, poor growth, intellectual disability, and hypohomocysteinemia. Congenital heart defects and liver involvement are variably present.

OMIM: 617744

Targets

nuclear factor, erythroid 2 like 2
Comments:  IMDDHH is associated with heterozygous missense mutations in the NFE2L2 gene. The mutations detected affect the N-terminal Neh2 domain of NRF2 that facilitates binding to inhibitory KEAP1 proteins (so KEAP1 inhibition of NRF2 is reduced), and this subsequently leads to chronic activation of NRF2-responsive stress response genes.
