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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:curation

The heterozygous p.Arg72Gln variant in FGF7 was identified by our study in 1 individual with autoinflammatory syndrome. While this gene is still lacking sufficient evidence to establish a gene-disease relationship, we believe this is a possible novel gene candidate for autoinflammatory syndrome. Given the limited information about this gene-disease relationship, the significance of the p.Arg72Gln variant is uncertain. If you have any additional information about functional evidence or other individuals with this phenotype that also have variants in FGF7 we encourage you to reach out to us. -
