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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.265 is higher than 0.05.
