Senior–Løken syndrome is an autosomal recessive inherited condition

Senior–Løken syndrome is a congenital eye disorder, first characterized in 1961.[1][2][3] It is a rare, ciliopathic, autosomal recessive disorder characterized by juvenile nephronophthis and progressive eye disease.[4]

Genetics

Genes involved include:

Type OMIM Genes
SLSN1 Online Mendelian Inheritance in Man (OMIM) 266900 NPHP1
SLSN3 Online Mendelian Inheritance in Man (OMIM) 606995 unknown
SLSN4 Online Mendelian Inheritance in Man (OMIM) 606996 NPHP4
SLSN5 Online Mendelian Inheritance in Man (OMIM) 609254 NPHP5/IQCB1[5]
SLSN6 Online Mendelian Inheritance in Man (OMIM) 610189 NPHP6/CEP290
SLSN7 Online Mendelian Inheritance in Man (OMIM) 613615 SDCCAG8

Pathophysiology

The cause of Senior–Løken syndrome type 5 has been identified to mutation in the NPHP1 gene which adversely affects the protein formation mechanism of the cilia.[6]

Relation to other rare genetic disorders

Recent findings in genetic research have suggested that a large number of genetic disorders, both genetic syndromes and genetic diseases, that were not previously identified in the medical literature as related, may be, in fact, highly related in the genetypical root cause of the widely varying, phenotypically-observed disorders. Such diseases are becoming known as ciliopathies. Known ciliopathies include primary ciliary dyskinesia, Bardet–Biedl syndrome, polycystic kidney and liver disease, nephronophthisis, Alström syndrome, Meckel–Gruber syndrome and some forms of retinal degeneration.[4]
