Fanconi anemia complementation group D2 — Definition
Fanconi anemisi tamamlama grubu D2 / Fanconi anemia complementation group D2
Fanconi anemia completion group D2 is a hereditary bone marrow failure syndrome that occurs as a result of mutations in the FANCD2 gene, which plays a role in DNA damage repair. The disease is characterized by progressive aplastic anemia, congenital anomalies and predisposition to cancer. Clinically, patients typically appear short-sized, thumb anomalies, brown spots on the skin and findings such as microcephalus. The diagnosis is verified by chromosome fracture test and genetic analysis.

🔬 Disease Definition
Fanconi anemisi, kemik iliği yetmezliği, doğumsal anomaliler ve kansere yatkınlık ile karakterize nadir bir genetik hastalıktır. FANCD2 genindeki mutasyonlar, DNA hasar onarımında rol oynayan FA/BRCA yolunu bozar.
🧬 Causes & Risk Factors
FANCD2 genindeki otozomal resesif mutasyonlar. Ailede hastalık öyküsü riski artırır.
🩺 Symptoms & Signs
Kemik iliği yetmezliği (anemi, enfeksiyon, kanama), doğumsal anomaliler (başparmak, iskelet, böbrek, kalp), ciltte kahverengi lekeler, boy kısalığı, mikrosefali, kanser yatkınlığı (özellikle AML ve skuamöz hücreli karsinom).
📋 Diagnostic Methods
Klinik bulgular, aile öyküsü, diepoksibütan (DEB) veya mitomisin C ile kromozom kırılma testi, FANCD2 gen mutasyon analizi.
💊 Treatment Options
Androjenler (kemik iliği stimülasyonu), büyüme faktörleri, kemik iliği nakli (hematopoetik kök hücre nakli), kanser tedavisi (cerrahi, kemoterapi, radyoterapi).
⚠️ Complications
Kemik iliği yetmezliği, lösemi ve solid tümörler, tedaviye bağlı toksisite (özellikle kemoterapi ve radyoterapiye aşırı duyarlılık).
