Congenital ocular motor apraxia, the NPHP1 gene, and surveillance for nephronophthisis.J AAPOS. 2013 Jun; 17(3):332-3.JA
We present an 11-month-old girl with congenital ocular motor apraxia (COMA) and Joubert syndrome found to have a compound heterozygous mutation in the NPHP1 gene that is responsible for juvenile nephronophthisis type 1. The association of congenital ocular motor apraxia and juvenile nephronophthisis is reviewed. The patient does not currently manifest signs of renal failure, although her mutation indicates that she is at risk for the development of juvenile nephronophthisis type 1.
