Genes affected

LAIR2 (HGNC:6478): (leukocyte associated immunoglobulin like receptor 2) The protein encoded by this gene is a member of the immunoglobulin superfamily. It was identified by its similarity to leukocyte-associated immunoglobulin-like receptor 1, a membrane-bound receptor that modulates innate immune response. The protein encoded by this locus is a soluble receptor that may play roles in both inhibition of collagen-induced platelet aggregation and vessel formation during placental implantation. This gene maps to a region of 19q13.4, termed the leukocyte receptor cluster, which contains 29 genes in the immunoglobulin superfamily. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Sep 2013]

The c.413C>G (p.A138G) alteration is located in exon 4 (coding exon 4) of the LAIR2 gene. This alteration results from a C to G substitution at nucleotide position 413, causing the alanine (A) at amino acid position 138 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
