Genes affected

CD28 (HGNC:1653): (CD28 molecule) The protein encoded by this gene is essential for T-cell proliferation and survival, cytokine production, and T-helper type-2 development. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2011]

CD28 Gene-Disease associations (from GenCC):

• immunodeficiency 123 with HPV-related verrucosis

  Inheritance: AR Classification: MODERATE, LIMITED Submitted by: Ambry Genetics, ClinGen
