Genes affected

CD80 (HGNC:1700): (CD80 molecule) The protein encoded by this gene is a membrane receptor that is activated by the binding of CD28 or CTLA-4. The activated protein induces T-cell proliferation and cytokine production. This protein can act as a receptor for adenovirus subgroup B and may play a role in lupus neuropathy.

The c.781T>C (p.C261R) alteration is located in exon 5 (coding exon 4) of the CD80 gene. This alteration results from a T to C substitution at nucleotide position 781, causing the cysteine (C) at amino acid position 261 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
