Kalıtsal spastik parapleji tip 49 / hereditary spastic paraplegia 49
Calditional spastic paraplegia type 49 is a neurodegenerative disease characterized by progressive muscle hardness (spastisite) and weakness in lower limbs. Otozomal shows resesif inheritance and usually starts in early childhood. The disease is caused by mutations in the AP4B1 gene and leads to disorder in intracellular vecycle transportation.

Disease Definition

🔬 Disease Definition
Herediter spastik parapleji tip 49 (HSP49), TECPR2 genindeki mutasyonlardan kaynaklanan, otozomal resesif geçişli, nadir görülen nörodejeneratif bir hastalıktır. Progresif spastisite, kas güçsüzlüğü ve alt ekstremitelerde sertlik ile karakterizedir.
🧬 Causes & Risk Factors
TECPR2 genindeki homozigot veya bileşik heterozigot mutasyonlar, otozomal resesif kalıtım paterni gösterir. Bu gen, otofaji ve hücresel temizlik süreçlerinde rol oynar; mutasyonlar nöronal hasara yol açar.
🩺 Symptoms & Signs
Erken çocukluk döneminde başlayan yürüme güçlüğü, alt ekstremitelerde spastisite, hiperrefleksi, Babinski işareti, kas güçsüzlüğü, ekstansör plantar yanıt, skolyoz, pes kavus, idrar aciliyeti ve bilişsel gerilik.
📋 Diagnostic Methods
Klinik değerlendirme, aile öyküsü, nörolojik muayene, manyetik rezonans görüntüleme (MRG) ile spinal kord atrofisi veya ince korpus kallozum, genetik test ile TECPR2 gen mutasyonlarının saptanması.
💊 Treatment Options
Semptomatik tedavi: Baklofen, tizanidin gibi antispastik ilaçlar, fizik tedavi, ergoterapi, ortopedik cihazlar (yürüteç, tekerlekli sandalye), botulinum toksini enjeksiyonları, selektif dorsal rizotomi (nadiren).
⚠️ Complications
İlerleyici mobilite kaybı, kontraktürler, skolyoz, bası yaraları, idrar yolu enfeksiyonları, solunum problemleri, osteoporoz, düşme ve kırık riski.
