Genes affected

CD83 (HGNC:1703): (CD83 molecule) The protein encoded by this gene is a single-pass type I membrane protein and member of the immunoglobulin superfamily of receptors. The encoded protein may be involved in the regulation of antigen presentation. A soluble form of this protein can bind to dendritic cells and inhibit their maturation. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

Ambry Genetics

Nov 08, 2022

The c.64G>A (p.E22K) alteration is located in exon 2 (coding exon 2) of the CD83 gene. This alteration results from a G to A substitution at nucleotide position 64, causing the glutamic acid (E) at amino acid position 22 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
