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.

TIMMDC1 (HGNC:1321): (translocase of inner mitochondrial membrane domain containing 1) Located in mitochondrion and nucleoplasm. Implicated in nuclear type mitochondrial complex I deficiency 31. [provided by Alliance of Genome Resources, Apr 2022]
