Structure and function[edit]
The protein encoded by this gene is a member of the fibroblast growth factor receptor family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein would consist of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member binds acidic and basic fibroblast growth hormone and plays a role in bone development and maintenance. Mutations in this gene lead to craniosynostosis and multiple types of skeletal dysplasia. Alternative splicing occurs and additional variants have been described, including those utilizing alternate exon 8 rather than 9, but their full-length nature has not been determined.[2]
Disease linkage[edit]
Defects in the FGFR3 gene has been associated with several conditions, including:
- achondroplasia/hypochondroplasia
- thanatophoric dwarfism
- seborrheic keratosis[3]
- bladder cancer[4]
Interactions[edit]
Fibroblast growth factor receptor 3 has been shown to interact with FGF1[5][6] and FGF9.[5][6]

治療
- (参考1)
- 治療方針:初期治療、維持療法、再発・難反応期治療がある。
- 初期治療:
- 化学療法:MP療法と多剤併用療法があるが、後者は奏効率は高いが生存期間延長効果がないため、一般的にはMP療法を行う。化学療法のみで治癒は困難であり、プラトー(臓器障害を認めない状態が3ヶ月以上持続)に達した後に維持療法を行う。
-
- インターフェロン:無事象生存期間、全生存期間の中央値はそれぞれ6ヶ月、7ヶ月の延長効果があったが、副作用を考慮し必ずしも推奨されない。
- プレドニゾロン:50mg投与隔日投与でで有効性が認められたが、副作用の発現リスクが高くなるため日本ではあまり行われていない。
- サリドマイド(認可??):単剤で30%、デキサメタゾンとの併用で40-50%、化学療法との併用では50-60%の奏効率が報告されている。
- ボルテゾミブ(認可??):デキサメタゾンとの併用が推奨されている。副作用は末梢神経障害、血小板減少。
- レナリドマイド(認可??):サリドマイド誘導体。サリドマイドに比べて効果は高く、末梢神経障害、消化器症状、神経症状、DVT等の副作用が軽い。
-
- 口渇・意識障害など明らかな臨床症状:生理食塩水+ビスホスホネート点滴静注。ステロイドやカルシトニンを併用すると有効な場合もある。
- 腎障害:M蛋白による尿細管の障害、高カルシウム血症、高尿酸血症、アミロイドーシス、尿路感染症、骨髄腫細胞浸潤などで腎障害をきたす。輸液、アシドーシス補正、電解質補正、血液透析。腎障害がある場合の化学療法には腎障害の少ないVAD療法()かデキサメタゾン大量療法が推奨される。
- 心臓、腎臓、消化管、舌等の臓器に沈着し、臓器障害をきたす。約30%の症例にみられるが、有償状は10%未満。予後を規定する心機能をモニターするため、心エコーでフォローする。アミロイドーシス自体に対する有効な治療はなく、原疾患の治療を早くすることが必要である。
