Genes affected

FGL2 (HGNC:3696): (fibrinogen like 2) The protein encoded by this gene is a secreted protein that is similar to the beta- and gamma-chains of fibrinogen. The carboxyl-terminus of the encoded protein consists of the fibrinogen-related domains (FRED). The encoded protein forms a tetrameric complex which is stabilized by interchain disulfide bonds. This protein may play a role in physiologic functions at mucosal sites. [provided by RefSeq, Jul 2008]

The c.743G>A (p.G248E) alteration is located in exon 2 (coding exon 2) of the FGL2 gene. This alteration results from a G to A substitution at nucleotide position 743, causing the glycine (G) at amino acid position 248 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
