Genes affected

FGFBP2 (HGNC:29451): (fibroblast growth factor binding protein 2) This gene encodes a member of the fibroblast growth factor binding protein family. The encoded protein is a serum protein that is selectively secreted by cytotoxic lymphocytes and may be involved in cytotoxic lymphocyte-mediated immunity. An increase in the amount of gene product may be associated with atopic asthma and mild extrinsic asthma.[provided by RefSeq Staff, Oct 2008]

The c.668G>C (p.G223A) alteration is located in exon 1 (coding exon 1) of the FGFBP2 gene. This alteration results from a G to C substitution at nucleotide position 668, causing the glycine (G) at amino acid position 223 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
