Strong gene disease association: definitive by ClinGen 2022

Immunodeficiency characterized by selective T-cell defect

Childhood onset, severe (death prior to 2 without treatment)

Treatment:
Supportive care includes immediate intravenous immunoglobulin (IVIG) and antibacterial, antifungal, antiviral, and Pneumocystis jiroveci prophylaxis to control and reduce the occurrence of infections.
Allogeneic HSCT to reconstitute the immune system, preferably prior to the onset of infections.
Prevention of secondary complications: Use of irradiated, leukoreduced, cytomegalovirus (CMV)-safe blood products; deferment of immunizations until immune reconstitution; consideration for formula feeds in place of breast feeding until CMV status of mother is known.

Symptoms include recurrent infections, including severe lower respiratory infections and oral candidiasis, chronic diarrhea, and failure to thrive. Combined immunodeficiencies such as ZAP-70 deficiency or major histocompatibility complex (MHC) class I and II gene expression deficiency may not be detected with the TREC assay as T-cell development is intact beyond the point of T-cell receptor (TCR) gene recombination (PMID: 32579701)
