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.325G>T (p.A109S) alteration is located in exon 1 (coding exon 1) of the FGFBP2 gene. This alteration results from a G to T substitution at nucleotide position 325, causing the alanine (A) at amino acid position 109 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
