Otozomal dominant osteopetrozis tip 2 / autosomal dominant osteopetrosis 2
Otozomal dominant osteopetrozis type 2 is a rare genetic disease, which causes the bones to become abnormally dense and hard. This condition is characterized by a deterioration of bone destruction cells called osteoclast as a result of dysfunction, bone remodeling (reforming). The disease usually manifests itself in the adult era and can lead to complications such as fractures, osteomiyelite (chemic infection), anemia and vision or hearing loss. Autozomal manifests a dominant inheritance, meaning it is enough to cause a single mutant gene copy disease in a parent.
Disease Definition
🔬 Disease Definition
Osteoklast fonksiyon bozukluğuna bağlı kemik yoğunluğunda artış ile karakterize, otozomal dominant geçişli genetik bir hastalıktır. CLCN7 gen mutasyonu en sık nedendir.
🧬 Causes & Risk Factors
CLCN7 genindeki heterozigot mutasyonlar, klor kanalı fonksiyonunu bozarak osteoklastların kemik rezorpsiyonunu engeller.
🩺 Symptoms & Signs
Çoğu asemptomatiktir; bazı hastalarda kırıklar, osteomyelit, kraniyal sinir basısına bağlı işitme/görme kaybı, anemi, hepatosplenomegali görülebilir.
📋 Diagnostic Methods
Radyografide yaygın osteoskleroz, kemik dansitometrisinde yüksek BMD, genetik test ile CLCN7 mutasyonu saptanması.
💊 Treatment Options
Semptomatik tedavi: kırık yönetimi, dekompresyon cerrahisi, interferon gamma-1b, kortikosteroidler, kemik iliği transplantasyonu (ağır vakalarda).
⚠️ Complications
Patolojik kırıklar, osteomyelit, kraniyal sinir sıkışması, anemi, trombositopeni, hidrosefali.
