Genes affected

CD86 (HGNC:1705): (CD86 molecule) This gene encodes a type I membrane protein that is a member of the immunoglobulin superfamily. This protein is expressed by antigen-presenting cells, and it is the ligand for two proteins at the cell surface of T cells, CD28 antigen and cytotoxic T-lymphocyte-associated protein 4. Binding of this protein with CD28 antigen is a costimulatory signal for activation of the T-cell. Binding of this protein with cytotoxic T-lymphocyte-associated protein 4 negatively regulates T-cell activation and diminishes the immune response. Alternative splicing results in several transcript variants encoding different isoforms.[provided by RefSeq, May 2011]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.010063201).
• BP6: Variant 3-122109385-G-A is Benign according to our data. Variant chr3-122109385-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3140700.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High AC in GnomAd at 26 AD gene.

Ambry Genetics

Mar 04, 2024

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
