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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 09, 2024The c.877T>C (p.Y293H) alteration is located in exon 9 (coding exon 7) of the FGL1 gene. This alteration results from a T to C substitution at nucleotide position 877, causing the tyrosine (Y) at amino acid position 293 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
