Combined immunodeficiency (CID) describes a condition defined by the failure of the cellular and humoral immune system. The degree of this failure varies from nearly complete absence of the adaptive immune system in severe combined immunodeficiency (SCID), whenaffected children - if untreated - die within the first year of life due to overwhelming infections, to mild forms diagnosed based on numerical alterations mainly of the T cells. Profound CID (pCID) refers to disease entities which are associated with a high morbidity andmortality but do not lead to death within the first year. While the genetic background of most SCID related genes has been identified and new born screening programs have been started world wide to screen for these patients, the molecular origin of pCID is less wellunderstood and common screening tests often fail due to the heterogeneous origin of this group of diseases. Given the frequently autosomal-recessive trait of inheritance pCID is more often found in ethnic groups with a higher prevalence of consanguineous marriages.In a trilateral cooperation between physicians and scientists from Palestinian hospitals, Hadassah University in Israel and the Centre for Chronic Immunodeficiency in Germany DECIDE seeks to identify children with pCID, discover and evaluate the underlying molecularcause of their disease and thereby determine better treatment Options including hematopoietic stem cell transplantation (HSCT). Through the close combined effort we will describe the individual clinical, genetic and immunological side of the disease in detail. The discoveryof new genetic causes of pCID and their functional evaluation will not only be advantageous for the affected family, but it will provide new important information on diagnosis and therapy of this severe sickness to the whole field of immunodeficiency and often the newinsights even expand our comprehension of basic immunology. Through common educational programs DECIDE will increase the awareness of this disease group, build new facilities in Israel andPalestine for the diagnosis and research of human immunodeficiency and thus strengthen the long-term collaboration between Palestinian, Israeli and German physicians and scientists.

联合免疫缺陷（CID）描述了一种由细胞和体液免疫系统衰竭定义的疾病。这种失败的程度不同，从严重联合免疫缺陷（SCID）中几乎完全缺乏适应性免疫系统，当受影响的儿童-如果未经治疗-在生命的第一年内死于压倒性感染，到主要基于T细胞的数量变化诊断的轻度形式。深度CID（pCID）是指与高发病率和死亡率相关但在第一年内不导致死亡的疾病实体。虽然大多数SCID相关基因的遗传背景已经被确定，并且新生儿筛查计划已经在世界范围内启动以筛查这些患者，但pCID的分子起源还不太清楚，并且由于这组疾病的异质性起源，常规筛查测试经常失败。鉴于经常发生的常染色体隐性遗传特征，pCID更常见于近亲婚姻流行率较高的族裔群体，在巴勒斯坦医院、以色列哈达萨大学和德国慢性免疫缺陷中心的医生和科学家之间的三方合作中，DECIDE试图确定患有pCID的儿童，发现和评估其疾病的潜在分子原因，从而确定更好的治疗方案，包括造血干细胞移植（HSCT）。通过密切合作的努力，我们将详细描述疾病的个体临床，遗传和免疫方面。pCID新的遗传病因的发现及其功能评价不仅有利于患者的治疗，而且将为整个免疫缺陷领域提供诊断和治疗pCID的新的重要信息，这些新的发现甚至扩展了我们对基础免疫学的理解。通过共同的教育方案，该中心将提高对这一疾病群体的认识，在以色列和巴勒斯坦建立新的设施，用于人体免疫缺陷的诊断和研究，从而加强巴勒斯坦、以色列和德国医生和科学家之间的长期合作。
