Clinical Characteristics and Genetic Profiles of Severe Combined Immunodeficiency in China

September 1, 2014 updated by: Shanghai Children's Medical Center
Severe combined immunodeficiency (SCID), a rare primary immunodeficiency dieases (PID), is poorly characterized in mainland China. We meant to explore the patients with SCID refered to our hospital and summarize their clinical manifestations and genetic features.

Detailed Description

Diagnostic criteria were based on recommendations by the Pan-American Group for Immunodeficiency and the European Society for Immunodeficiencies, which included failure to thrive, persistent diarrhea, respiratory symptoms, and oral candidiasis, or Pneumocystis pneumonia, severe bacterial infections, and disseminated Bacillus Calmette-Guérin (BCG) infection during the first 2 to 7 months of life. In addition, patients included in the study were <2 years of age, with either transplacentally acquired maternal T cells or <20 % CD3+ T cells, the absolute lymphocyte count (ALC) <3000/mm3. Exclusion criteria include HIV infection, congenital rubella, DiGeorge syndrome, Zap70 deficiency, Cartilage hair hypoplasia, PNP deficiency and MHC class II deficiency.

Severe Combined Immunodeficiency
Case histories were analyzed to grasp important characteristics of the diseases. Distribution of lymphocyte subsets from peripheral blood were examined by flow cytometry. Amplify and identify exons from gene IL-2RG by PCR and agarose gel electrophoresis, and then followed by gene sequencing.
Genetic: gene sequencing
