title: [Pediatric neurology and genetics: introduction].
abstract: BACKGROUND
  Heredity plays a role in a large proportion of pediatric neurologic disorders, and the spectacular recent developments in molecular genetics have contributed to improved understanding of the basic causes of many diseases and neurodevelopmental abnormalities.
  
  
  OBJECTIVE
  To provide a brief introduction to certain genetic aspects of neuropediatrics.
  
  
  METHODS
  We consider the following aspects: 1) The importance of hereditary factors in pediatric neurology; 2) The different types of inheritance relevant in this context; 3) Nosologic, diagnostic and therapeutic implications of recent advances in molecular genetics; 4) Bioethical implications of the application of this new understanding.
  
  
  CONCLUSIONS
  Independently of enhanced treatment prospects, progress in molecular genetics has improved the nosology and diagnosis of many pediatric neurological disorders.
