Genes affected

TREML2 (HGNC:21092): (triggering receptor expressed on myeloid cells like 2) TREML2 is located in a gene cluster on chromosome 6 with the single Ig variable (IgV) domain activating receptors TREM1 (MIM 605085) and TREM2 (MIM 605086), but it has distinct structural and functional properties (Allcock et al., 2003 [PubMed 12645956]).[supplied by OMIM, Mar 2008]

The c.747A>T (p.R249S) alteration is located in exon 3 (coding exon 3) of the TREML2 gene. This alteration results from a A to T substitution at nucleotide position 747, causing the arginine (R) at amino acid position 249 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
