Genes affected

FGF1 (HGNC:3665): (fibroblast growth factor 1) The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Multiple alternatively spliced variants encoding different isoforms have been described. [provided by RefSeq, Jan 2009]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.268G>A (p.G90S) alteration is located in exon 4 (coding exon 2) of the FGF1 gene. This alteration results from a G to A substitution at nucleotide position 268, causing the glycine (G) at amino acid position 90 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
