Genes affected

FGF7 (HGNC:3685): (fibroblast growth factor 7) 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 protein is a potent epithelial cell-specific growth factor, whose mitogenic activity is predominantly exhibited in keratinocytes but not in fibroblasts and endothelial cells. Studies of mouse and rat homologs of this gene implicated roles in morphogenesis of epithelium, reepithelialization of wounds, hair development and early lung organogenesis.

Ambry Genetics

Mar 30, 2024

The c.68G>T (p.C23F) alteration is located in exon 2 (coding exon 1) of the FGF7 gene. This alteration results from a G to T substitution at nucleotide position 68, causing the cysteine (C) at amino acid position 23 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
