Retinal disorders
Gene: NPHP3
Comment on list classification: Two recent papers showing recessive mutations cause non-syndromic RP.Created: 7 Jun 2016, 12:10 p.m.
This gene is on the Manchester Genetic Retinal Degeneration Conditions panel (covers known genes for isolated progessive retinal degeneration, Leber congenital amaurosis, macular dystrophy, achromatopsia, congenital stationary night blindness as well as the two most common causes of syndromic blindess Usher and Bardet-Biedl syndromes and additional syndromes including Joubert, Senior-Loken, and Cohen syndrome.Created: 2 Jun 2016, 8:06 a.m.
Publication by Omran et al 2002 linking NPHP3 to Senior-Loken syndrome which involves RP or LCA.
Reports in HGMD are predominantly in patients with nephronophtisis and we have not identified NPHP3 mutations in a disease-causing state in-house. Therefore unclear how relevant this gene is to this panel.Created: 1 Jun 2016, 10:13 a.m.

Nephrol. 13: 75-79; NPHP3 mutations have been linked to Senior-Loken syndrome, which involves cystic kidney disease (nephronophthisis) and retinitis pigmentosa or Leber congenital amaurosis.
