Senior-Loken syndrome 1 


An autosomal recessive disorder (OMIM:266900) characterised by nephronophthisis—progressive atrophy of nephrons, variably accompanied by medullary cystic renal disease, and Leber congenital amaurosis—progressive retinal degeneration, appearing in the first year of life.

Molecular pathology Defects in NPHP1, which encodes a protein that plays a role in controlling cell division, in cell-cell and cell-matrix adhesion signaling, epithelial cell polarity, in organising apical junctions in kidney cells, in regulating intraflagellar transport during ciliogenesis, in retina development, and in spermatogenesis, cause Senior-Loken syndrome 1.
