BabyScreen+ newborn screening v0.2048 RAC2 Zornitza Stark Gene: rac2 has been classified as Green List (High Evidence).
BabyScreen+ newborn screening v0.2048 RAC2 Zornitza Stark Phenotypes for gene: RAC2 were changed from Immunodeficiency 73B with defective neutrophil chemotaxis and lymphopaenia MIM# 618986 to Immunodeficiency 73B with defective neutrophil chemotaxis and lymphopenia MIM# 618986
BabyScreen+ newborn screening v0.2047 RAC2 Zornitza Stark Classified gene: RAC2 as Green List (high evidence)
BabyScreen+ newborn screening v0.2047 RAC2 Zornitza Stark Gene: rac2 has been classified as Green List (High Evidence).
BabyScreen+ newborn screening v0.2046 RAC2 Zornitza Stark gene: RAC2 was added
gene: RAC2 was added to Baby Screen+ newborn screening. Sources: Expert list
treatable, immunological tags were added to gene: RAC2.
Mode of inheritance for gene: RAC2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Phenotypes for gene: RAC2 were set to Immunodeficiency 73B with defective neutrophil chemotaxis and lymphopaenia MIM# 618986
Review for gene: RAC2 was set to GREEN
Added comment: Immunodeficiency 73B with defective neutrophil chemotaxis and lymphopaenia
13 individuals from 8 unrelated families; mono-allelic; gain of function; multiple mouse models

Mono-allelic missense variants were reported in each individual (5 x De Novo) and resulted in a gain-of -function. (E62K, P34H, N92T, G12R)

These individuals typically presented in infancy with frequent infections, profound leukopaenia, lymphopaenia diarrhoea and hypogammaglobulinaemia.

SCID-like phenotype.

Treatment: IVIG, BMT

Note evidence for the other two immunodeficiency disorders associated with this gene is limited.
