CD247
- Autosomal recessive (AR) transmission.
- It is caused by homozygous mutation in the CD247 (CD3Z) gene on chromosome 1.[10]
CD45 deficiency
- Autosomal recessive (AR) transmission.
- It is caused by mutation in the CD45 gene on chromosome 1.[11]
Coronin-1A deficiency
- Autosomal recessive (AR) transmission.
- It is caused by mutation in the CORO1A gene (which encodes an actin-regulating protein that is expressed mainly in hematopoietic cells) on chromosome 16.[12]
Winged helix deficiency/Nude SCID
- Autosomal recessive (AR) transmission.
- It is caused by a mutation in the FOXN1 gene (a transcription factor essential for the development and function of thymic epithelial cells) on chromosome 17. [13][14]
- Patients usually have the clinical triad of athymia, congenital alopecia universalis and nail dystrophy and present in early few months of life with severe, recurrent infections.[15]CNS defects have also been reported which include anencephaly and spina bifida.[16]
- Initial management includes immediate referral to a specialist center in suspected patients and providing supportive care until a definitive diagnosis reached.[17]
- Prophylaxis and early treatment of infections is also an important step in management.[18]
ADA deficiency
- Autosomal recessive (AR) transmission.
- It is caused by homozygous or compound heterozygous mutation in the adenosine deaminase gene (ADA) on chromosome 20.
- Patients have chondrosternal dysplasia, neurologic abnormalities like movement disorders, nystagmus, sensorineural deafness and cognitive defects, and also hepatic dysfucnction.[19][20][21]
- Treatment options include:
- Enzyme replacement therapy: Pegademase bovine (PEG-ADA) is used as the replacement therapy.[22]
- Bone marrow transplantation.[23]
Reticular dysgenesis
- Autosomal recessive (AR) transmission.
- It is caused by homozygous or compound heterozygous mutation in the mitochondrial adenylate kinase-2 gene (AK2) on chromosome 1.
- Patients present with agranulocytosis, lymphopenia and sensorineural hearing loss.
- Bone marrow transplant is the treatment of choice.[24]
DNA Ligase IV deficiency
- Autosomal recessive (AR) transmission.
- It is caused by homozygous or compound heterozygous mutation in the LIG4 gene on chromosome 13.
- Patients show unusual facial features, microcephaly, developmental delay, pancytopenia, and various skin abnormalities.[25]
CERNUNNOS/XLF deficiency
- Autosomal recessive (AR) transmission.
- It is caused by mutations in the NHEJ1 gene on chromosome 2.
- It is characterized by microcephaly, growth retardation and sensitivity to ionizing radiation.[26]
DNA PKcs deficiency
- Autosomal recessive (AR) transmission.
- It is caused by a mutation in the PRKDC gene on chromosome 8.[27]
RAG 1/2 deficiency
- Autosomal recessive (AR) transmission.
- It is caused by homozygous or compound heterozygous mutations in the RAG1 and RAG2 genes on chromosome 11.[28]
- Patients present with persistent diarrhea, candidiasis, lung infections, fever, and opportunistic infections.[29]
DCLRE1C deficiency
- Autosomal recessive (AR) transmission.
- It is caused by mutation in the gene encoding Artemis in chromosome 10.[30]
Combined Immunodeficiencies Generally Less Pronounced than Severe Combined Immunodeficiency
MHC II Deficiency
- MHC class II deficiency, called as the bare lymphocyte syndrome type II.
- a rare autosomal recessive disorder.
- Lack of constitutive and inducible MHC class II expression in all cell types and tissues.[31]
MAGT 1 Def:,LCK Def:, UNC119 Def:
- Magnesium transporter gene (MAGT1) deficiency, T-cell tyrosine kinase Lck deficiency and Signaling adaptor protein Uncoordinated 119 (Unc119) deficiency related with a condition called Idiopathic CD4 lymphopenia. [32]
- MAGT1 deficiency stops the Mg(2+) influx, which impairs responses to antigen receptor engagement and successive steps like activation of phospholipase Cγ1 and Ca(2+) influx in T cells but not B cells.[33]
- Lck is vital for both CD4 and CD8 T-cell development and function. LCK deficiency decrease T cell proliferation.[34]
- Unc119 is necessary for activation of T-cell tyrosine kinase Lck. Unc119-deficiency reduce the activity of LCK and decrease interleukin 2 production and cellular proliferation.[35]
CD8 deficiency
- CD8 glycoproteins play vital role in both the maturation and function of MHC class I-restricted T lymphocytes.
- CD8 deficiency is autosomal recessive familial condition.
- Single mutation in the CD8α gene that is due to missense mutation (gly90-->ser) in both alleles of the immunoglobulin domain of the CD8 alpha gene[36]
ZETA-CHAIN-ASSOCIATED PROTEIN KINASE 70 (ZAP70) Deficiency
- ZAP70 gene encodes a tyrosine kinase that is important for T-cell signaling.
- ZAP70 deficiency, results in loss of the activity of this kinase[37]
- ZAP70 is expressed mostly in T and NK cells, deficiency causes dysregulated T cells[38]
MHC1 deficiency
- Autosomal recessive condition also called as Bare lymphocyte syndrome type I.
- Extremely rare condition, less than 30 patients reported worldwide[39]
- Homozygous inactivating mutation of transporter associated with antigen processing (TAP), which helps in peptide loading on MHC1.
