Topics are discussed with reference to specific human genetic diseases. Most disorders are autosomal recessive in transmission Most disorders are evident at or soon after birth. Leukopenia is also present. It is important for paediatricians and neonatologists to keep in mind inborn errors of metabolism (IEMs) as a cause of illness in the neonatal period, as many disorders are treatable and, in most cases, successful outcome is dependent on a rapid diagnosis and early instigation of therapy. Newborns are now screened for many treatable metabolic disorders, but these screening tests may miss milder presentations of treatable inborn errors of metabolism that present later in life.
