Genes affected

FGL1 (HGNC:3695): (fibrinogen like 1) Fibrinogen-like 1 is a member of the fibrinogen family. This protein is homologous to the carboxy terminus of the fibrinogen beta- and gamma- subunits which contains the four conserved cysteines of fibrinogens and fibrinogen related proteins. However, this protein lacks the platelet-binding site, cross-linking region and a thrombin-sensitive site which are necessary for fibrin clot formation. This protein may play a role in the development of hepatocellular carcinomas. Four alternatively spliced transcript variants encoding the same protein exist for this gene.

The c.867T>G (p.H289Q) alteration is located in exon 9 (coding exon 7) of the FGL1 gene. This alteration results from a T to G substitution at nucleotide position 867, causing the histidine (H) at amino acid position 289 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
