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]

The c.428C>T (p.A143V) alteration is located in exon 4 (coding exon 4) of the CD83 gene. This alteration results from a C to T substitution at nucleotide position 428, causing the alanine (A) at amino acid position 143 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
