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.545C>T (p.A182V) alteration is located in exon 3 (coding exon 3) of the FGF21 gene. This alteration results from a C to T substitution at nucleotide position 545, causing the alanine (A) at amino acid position 182 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
