| Disease ID | Source | Name | Description |
| 613834 | OMIM | Multisystemic smooth muscle dysfunction syndrome (MSMDS) | A syndrome characterized by dysfunction of smooth muscle cells throughout the body, leading to aortic and cerebrovascular disease, fixed dilated pupils, hypotonic bladder, malrotation, and hypoperistalsis of the gut and pulmonary hypertension. The disease is caused by variants affecting the gene represented in this entry. |
| 614042 | OMIM | Moyamoya disease 5 (MYMY5) | A progressive cerebral angiopathy characterized by bilateral intracranial carotid artery stenosis and telangiectatic vessels in the region of the basal ganglia. The abnormal vessels resemble a 'puff of smoke' (moyamoya) on cerebral angiogram. Affected individuals can develop transient ischemic attacks and/or cerebral infarction, and rupture of the collateral vessels can cause intracranial hemorrhage. Hemiplegia of sudden onset and epileptic seizures constitute the prevailing presentation in childhood, while subarachnoid bleeding occurs more frequently in adults. The disease is caused by variants affecting the gene represented in this entry. |
| 611788 | OMIM | Aortic aneurysm, familial thoracic 6 (AAT6) | A disease characterized by permanent dilation of the thoracic aorta usually due to degenerative changes in the aortic wall. It is primarily associated with a characteristic histologic appearance known as 'medial necrosis' or 'Erdheim cystic medial necrosis' in which there is degeneration and fragmentation of elastic fibers, loss of smooth muscle cells, and an accumulation of basophilic ground substance. The disease is caused by variants affecting the gene represented in this entry. |
