Involvement in diseasei

Senior-Loken syndrome 7 (SLSN7)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA renal-retinal disorder characterized by progressive wasting of the filtering unit of the kidney (nephronophthisis), with or without medullary cystic renal disease, and progressive eye disease. Typically this disorder becomes apparent during the first year of life.

See also OMIM:613615
Bardet-Biedl syndrome 16 (BBS16)2 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA 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.
