Genes affected

FGFR4 (HGNC:3691): (fibroblast growth factor receptor 4) The protein encoded by this gene is a tyrosine kinase and cell surface receptor for fibroblast growth factors. The encoded protein is involved in the regulation of several pathways, including cell proliferation, cell differentiation, cell migration, lipid metabolism, bile acid biosynthesis, vitamin D metabolism, glucose uptake, and phosphate homeostasis. This protein consists of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment, and a cytoplasmic tyrosine kinase domain. The extracellular portion interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation.

Collection Method:clinical testing

The c.253C>T (p.R85C) alteration is located in exon 3 (coding exon 2) of the FGFR4 gene. This alteration results from a C to T substitution at nucleotide position 253, causing the arginine (R) at amino acid position 85 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
