What genetic syndrome is associated with retinal capillary hemangioblastoma?

Von Hippel-Lindau disease is a genetic syndrome characterized by the development of various tumors and cysts, including retinal capillary hemangioblastomas, which are benign vascular tumors that can occur in the retina. This syndrome is caused by mutations in the VHL gene, which is a tumor suppressor gene located on chromosome 3. Individuals with Von Hippel-Lindau disease may also be at risk for developing other types of tumors, such as renal cell carcinoma and pheochromocytomas.

The association of retinal capillary hemangioblastomas with Von Hippel-Lindau disease is significant, as these lesions can lead to vision impairment if not monitored or treated appropriately. The presence of these tumors is often one of the early clinical manifestations of the syndrome, making regular ophthalmic examination critical for early detection.

In contrast, other syndromes listed, such as Marfan syndrome, neurofibromatosis, and Li-Fraumeni syndrome, do not commonly include retinal capillary hemangioblastomas among their features. Marfan syndrome is primarily associated with connective tissue abnormalities, neurofibromatosis relates to nerve sheath tumors and other neurocutaneous manifestations, and Li-Fraumeni syndrome is linked to a predisposition to various cancers but
