Genes affected

TRIB1 (HGNC:16891): (tribbles pseudokinase 1) Enables mitogen-activated protein kinase kinase binding activity and protein kinase inhibitor activity. Involved in several processes, including JNK cascade; negative regulation of lipopolysaccharide-mediated signaling pathway; and regulation of protein kinase activity. Located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Sep 07, 2022

The c.520C>T (p.R174W) alteration is located in exon 2 (coding exon 2) of the TRIB1 gene. This alteration results from a C to T substitution at nucleotide position 520, causing the arginine (R) at amino acid position 174 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
