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.622G>A (p.D208N) alteration is located in exon 5 (coding exon 5) of the CD200R1 gene. This alteration results from a G to A substitution at nucleotide position 622, causing the aspartic acid (D) at amino acid position 208 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
