Genes affected

TREM1 (HGNC:17760): (triggering receptor expressed on myeloid cells 1) This gene encodes a receptor belonging to the Ig superfamily that is expressed on myeloid cells. This protein amplifies neutrophil and monocyte-mediated inflammatory responses triggered by bacterial and fungal infections by stimulating release of pro-inflammatory chemokines and cytokines, as well as increased surface expression of cell activation markers. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Jun 2011]

The c.170T>C (p.I57T) alteration is located in exon 2 (coding exon 2) of the TREM1 gene. This alteration results from a T to C substitution at nucleotide position 170, causing the isoleucine (I) at amino acid position 57 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
