Genes affected

FGF19 (HGNC:3675): (fibroblast growth factor 19) The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes including embryonic development cell growth, morphogenesis, tissue repair, tumor growth and invasion. This growth factor is a high affinity, heparin dependent ligand for FGFR4. Expression of this gene was detected only in fetal but not adult brain tissue. Synergistic interaction of the chick homolog and Wnt-8c has been shown to be required for initiation of inner ear development. [provided by RefSeq, Jul 2008]

The c.550G>A (p.E184K) alteration is located in exon 3 (coding exon 3) of the FGF19 gene. This alteration results from a G to A substitution at nucleotide position 550, causing the glutamic acid (E) at amino acid position 184 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
