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.788C>T (p.P263L) alteration is located in exon 6 (coding exon 6) of the CD200 gene. This alteration results from a C to T substitution at nucleotide position 788, causing the proline (P) at amino acid position 263 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
