Genes affected
FGFBP1 (HGNC:19695): (fibroblast growth factor binding protein 1) This gene encodes a secreted fibroblast growth factor carrier protein. The encoded protein plays a critical role in cell proliferation, differentiation and migration by binding to fibroblast growth factors and potentiating their biological effects on target cells. The encoded protein may also play a role in tumor growth as an angiogenic switch molecule, and expression of this gene has been associated with several types of cancer including pancreatic and colorectal adenocarcinoma. A pseudogene of this gene is also located on the short arm of chromosome 4. [provided by RefSeq, Nov 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 13, 2023The c.504G>A (p.M168I) alteration is located in exon 2 (coding exon 1) of the FGFBP1 gene. This alteration results from a G to A substitution at nucleotide position 504, causing the methionine (M) at amino acid position 168 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
