Classification

Immunodeficiency disorders are classified into two types:

• Primary immunodeficiency
• Secondary immunodeficiency

Primary immunodeficiency:

Primary immunodeficiency disorders
Phagocyte cell defects	Decreased number Functional Defects	Schwachman-Diamond Syndrome G6PC3 deficiency Cohen Syndrome Barth Syndrome Glycogen Storage Disease Type 1b Clericuzio Syndrome VPS45 deficiency P14/LAMTOR2 deficiency JAGN1 deficiency 3-methylglutaconic aciduria SMARCD2 deficiency WDR1 deficiency HYOU1 deficiency Elastase deficiency HAX1 deficiency(Kostmann Disease) GFI1 deficiency G-CSF receptor deficiency X-linked neutropenia /mylodysplasia WAS GOF Neutropenia with combined immune deficiency Cystic Fibrosis Papillion-Lefèvre Localized juvenile peridontitis B-Actin Leukocyte adhesion deficiency GATA2 def (MonoMac sd) Specific granule deficiency Pulmonary alveolar proteinosis Chronic Granulomatous Disease Rac 2 def G6PD def Class 1
Defects in Intrinsic and Innate immunity	Predisposition to bacterial infections
