Genes affected

CD200R1 (HGNC:24235): (CD200 receptor 1) This gene encodes a receptor for the OX-2 membrane glycoprotein. Both the receptor and substrate are cell surface glycoproteins containing two immunoglobulin-like domains. This receptor is restricted to the surfaces of myeloid lineage cells and the receptor-substrate interaction may function as a myeloid downregulatory signal. Mouse studies of a related gene suggest that this interaction may control myeloid function in a tissue-specific manner. Alternative splicing of this gene results in multiple transcript variants.

The c.766C>T (p.P256S) alteration is located in exon 5 (coding exon 5) of the CD200R1 gene. This alteration results from a C to T substitution at nucleotide position 766, causing the proline (P) at amino acid position 256 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
