Summary

N syndrome is characterised by intellectual deficit, deafness, ocular anomalies, T-cell leukaemia, cryptorchidism, hypospadias and spasticity. Three cases have been described so far. Mutations in DNA polymerase alpha, leading to increased chromosome breakage, may be responsible for the syndrome. X-linked recessive transmission has been proposed. *Author: Orphanet (November 2006)*.
