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]

The c.116G>C (p.S39T) alteration is located in exon 2 (coding exon 2) of the CD28 gene. This alteration results from a G to C substitution at nucleotide position 116, causing the serine (S) at amino acid position 39 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
