| Disease ID | Source | Name | Description |
| 619111 | OMIM | COACH syndrome 2 (COACH2) | A form of COACH syndrome, a disorder characterized by cerebellar vermis hypoplasia, developmental delay, impaired intellectual development, ataxia, and hepatic fibrosis. Patients present the molar tooth sign, a midbrain-hindbrain malformation pathognomonic for Joubert syndrome and related disorders. Other features, such as coloboma and renal cysts, may be variable. COACH2 inheritance is autosomal recessive. The disease is caused by variants affecting the gene represented in this entry. |
| 612284 | OMIM | Meckel syndrome 6 (MKS6) | A disorder characterized by a combination of renal cysts and variably associated features including developmental anomalies of the central nervous system (typically encephalocele), hepatic ductal dysplasia and cysts, and polydactyly. The disease is caused by variants affecting the gene represented in this entry. |
| 612285 | OMIM | Joubert syndrome 9 (JBTS9) | A disorder presenting with cerebellar ataxia, oculomotor apraxia, hypotonia, neonatal breathing abnormalities and psychomotor delay. Neuroradiologically, it is characterized by cerebellar vermian hypoplasia/aplasia, thickened and reoriented superior cerebellar peduncles, and an abnormally large interpeduncular fossa, giving the appearance of a molar tooth on transaxial slices (molar tooth sign). Additional variable features include retinal dystrophy and renal disease. The disease is caused by variants affecting the gene represented in this entry. |
