Genes affected

CD200 (HGNC:7203): (CD200 molecule) This gene encodes a type I membrane glycoprotein containing two extracellular immunoglobulin domains, a transmembrane and a cytoplasmic domain. This gene is expressed by various cell types, including B cells, a subset of T cells, thymocytes, endothelial cells, and neurons. The encoded protein plays an important role in immunosuppression and regulation of anti-tumor activity. Alternative splicing results in multiple transcript variants encoding different isoforms.

The c.8G>C (p.R3T) alteration is located in exon 1 (coding exon 1) of the CD200 gene. This alteration results from a G to C substitution at nucleotide position 8, causing the arginine (R) at amino acid position 3 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
