The patient can also experience damage or loss of teeth. Obvious signs
Most obvious sign is gingival overgrowth (overgrowth of the gums)
Hindered chewing efficiency and difficulties eating
Increasing mobility of teeth
Abnormally shaped teeth and abnormal movement of teeth
Inflammation and/or swelling of the gums/gingiva
Not necessarily any signs of pain but experiencing pain is possible
Difficulties in speaking, oftentimes can lead to speech disorders
Other dental and oral problems
In some cases, Hereditary Gingival Fibromatosis may cause bleeding from the gums, or gum ulcerations. Cause
Though much more research needs to be done, researchers have mostly agreed that a mutation in SOS1, son-of-sevenless gene, is responsible for this disease. SOS1 is a guanine nucleotide-exchange factor that functions in the transduction of signals that control cell growth and differentiation. A mutation in the SOS1 gene results in a single nucleotide insertion. Specific linkage studies have localized the mutation for isolated, nonsyndromic autosomal dominant forms of gingival fibromatosis to chromosomes 2 and 5, more specifically 2p21-p22 and 5q13-q22. Genetic
HGF1 - Caused by a mutation in the SOS1 gene localized on chromosome 2p21-p22HGF2 - Caused by a mutation in the SOS1 gene localized on chromosome 5q13-q22Mutations in the RE1-silencing transcription factor (REST) gene can also cause this syndrome. Non genetic
HGF may also be caused by unwanted side effects of pharmacological agents like phenytoin, ciclosporin, and some calcium-channel blockers, meaning HGF is a disease that can be drug-induced. However, there is little next to no research done in this area to support the claim.
