Discovery of single-gene inborn errors of immunity by next generation sequencing.

Discovery of single-gene inborn errors of immunity by next generation sequencing. Curr Opin Immunol. 2014 May 30;30C:17-23 Authors: Conley ME, Casanova JL Abstract Many patients with clinical and laboratory evidence of primary immunodeficiency do not have a gene specific diagnosis. The use of next generation sequencing, particularly whole exome sequencing, has given us an extraordinarily powerful tool to identify the disease-causing genes in some of these patients. At least 34 new gene defects have been identified in the last 4 years. These findings document the striking heterogeneity of the phenotype in patients with mutations in the same gene. In some cases this can be attributed to loss-of-function mutations in some patients, but gain-of-function mutations in others. In addition, the surprisingly high frequency of autosomal dominant immunodeficiencies with variable penetrance, and de novo mutations in disorders with a severe phenotype has been unmasked.
