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.787T>C (p.S263P) alteration is located in exon 6 (coding exon 6) of the CD200R1 gene. This alteration results from a T to C substitution at nucleotide position 787, causing the serine (S) at amino acid position 263 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
