Genes affected

FGF21 (HGNC:3678): (fibroblast growth factor 21) Theis gene encodes 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. This protein is a secreted endocrine factor that functions as a major metabolic regulator. The encoded protein stimulates the uptake of glucose in adipose tissue. [provided by RefSeq, Mar 2016]

The c.472C>G (p.P158A) alteration is located in exon 3 (coding exon 3) of the FGF21 gene. This alteration results from a C to G substitution at nucleotide position 472, causing the proline (P) at amino acid position 158 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
