Gingival Fibromatosis, also known as hereditary gingival fibromatosis, is related to fibromatosis, gingival, 1 and fibromatosis. An important gene associated with Gingival Fibromatosis is SOS1 (SOS Ras/Rac Guanine Nucleotide Exchange Factor 1), and among its related pathways/superpathways are Transcription Androgen Receptor nuclear signaling and Regulation of Insulin-like Growth Factor (IGF) transport and uptake by Insulin-like Growth Factor Binding Proteins (IGFBPs). Affiliated tissues include tongue and pituitary, and related phenotypes are gingival overgrowth and gingival fibromatosis
