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.

Collection Method: clinical testing

The c.857G>A (p.R286H) alteration is located in exon 6 (coding exon 5) of the CD80 gene. This alteration results from a G to A substitution at nucleotide position 857, causing the arginine (R) at amino acid position 286 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
