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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 13, 2023The c.991G>A (p.E331K) alteration is located in exon 3 (coding exon 3) of the TRIB1 gene. This alteration results from a G to A substitution at nucleotide position 991, causing the glutamic acid (E) at amino acid position 331 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
