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]
CCDC146 (HGNC:29296): (coiled-coil domain containing 146) Located in centriole. [provided by Alliance of Genome Resources, Apr 2022]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 05, 2024The 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. -
