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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2023The c.190C>T (p.R64C) alteration is located in exon 1 (coding exon 1) of the FGFBP2 gene. This alteration results from a C to T substitution at nucleotide position 190, causing the arginine (R) at amino acid position 64 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
