Genes affected

FIBP (HGNC:3705): (FGF1 intracellular binding protein) Acidic fibroblast growth factor is mitogenic for a variety of different cell types and acts by stimulating mitogenesis or inducing morphological changes and differentiation. The FIBP protein is an intracellular protein that binds selectively to acidic fibroblast growth factor (aFGF). It is postulated that FIBP may be involved in the mitogenic action of aFGF. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.967G>A (p.D323N) alteration is located in exon 9 (coding exon 9) of the FIBP gene. This alteration results from a G to A substitution at nucleotide position 967, causing the aspartic acid (D) at amino acid position 323 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
