| Disease ID | Source | Name | Description |
| 610688 | OMIM | Joubert syndrome 6 (JBTS6) | 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. |
| 613550 | OMIM | Nephronophthisis 11 (NPHP11) | A disorder characterized by the association of nephronophthisis with hepatic fibrosis. Nephronophthisis is a progressive tubulo-interstitial kidney disorder histologically characterized by modifications of the tubules with thickening of the basement membrane, interstitial fibrosis and, in the advanced stages, medullary cysts. Typical clinical features are chronic renal failure, anemia, polyuria, polydipsia, isosthenuria, and growth retardation. Associations with extrarenal symptoms, especially ocular lesions, are frequent. The disease is caused by variants affecting the gene represented in this entry. |
| 602152 | OMIM | RHYNS syndrome (RHYNS) | An autosomal recessive syndrome characterized by gaze palsy, retinitis pigmentosa, sensorineural hearing loss, hypopituitarism, nephronophthisis, and skeletal dysplasia. The disease is caused by variants affecting the gene represented in this entry. |
| 216360 | OMIM | COACH syndrome 1 (COACH1) | 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. COACH1 inheritance is autosomal recessive. The disease is caused by variants affecting the gene represented in this entry. |
| 607361 | OMIM | Meckel syndrome 3 (MKS3) | 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. |
| 615991 | OMIM | Bardet-Biedl syndrome 14 (BBS14) | A syndrome characterized by usually severe pigmentary retinopathy, early-onset obesity, polydactyly, hypogenitalism, renal malformation and mental retardation. Secondary features include diabetes mellitus, hypertension and congenital heart disease. Bardet-Biedl syndrome inheritance is autosomal recessive, but three mutated alleles (two at one locus, and a third at a second locus) may be required for clinical manifestation of some forms of the disease. The gene represented in this entry may act as a disease modifier. TMEM67 variations may influence the expression of Bardet-Biedl syndrome in patients who have causative mutations in other genes. Heterozygosity for a complex mutation in the TMEM67 gene coding for a protein with 2 in cis changes, and homozygosity for a truncating mutation of the CEP290 gene has been found in a patient with Bardet-Biedl syndrome 14. |
