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.307T>G (p.Y103D) alteration is located in exon 2 (coding exon 2) of the CD28 gene. This alteration results from a T to G substitution at nucleotide position 307, causing the tyrosine (Y) at amino acid position 103 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
