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]

Ambry Genetics

Nov 21, 2022

The c.944A>G (p.Y315C) alteration is located in exon 5 (coding exon 5) of the TREML2 gene. This alteration results from a A to G substitution at nucleotide position 944, causing the tyrosine (Y) at amino acid position 315 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
