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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 21, 2021The c.683C>T (p.T228M) alteration is located in exon 4 (coding exon 4) of the TREM1 gene. This alteration results from a C to T substitution at nucleotide position 683, causing the threonine (T) at amino acid position 228 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
