Genes affected

LILRA4 (HGNC:15503): (leukocyte immunoglobulin like receptor A4) This gene encodes an immunoglobulin-like cell surface protein that is expressed predominantly on plasmacytoid dendritic cells (PDCs) and modulates the function of these cells in the immune response. Expression of this gene is downregulated by interleukin 3 (IL3). This gene is one of a cluster of highly related genes located at chromosomal region 19q13.4. [provided by RefSeq, Jan 2015]

The c.1348A>G (p.M450V) alteration is located in exon 8 (coding exon 8) of the LILRA4 gene. This alteration results from a A to G substitution at nucleotide position 1348, causing the methionine (M) at amino acid position 450 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
