Phenylketonurias

Fenylketonuri

Svensk definition

En grupp autosomalt recessiva sjukdomar, vars kännetecken är brist på leverenzymet fenylalaninhydroxylas, eller mindre ofta nedsatt verkan av dihydropteridinreduktas (atypisk fenylketonuri). Klassisk fenylketonuri orskas av svår brist på fenylalaninhydroxylas och yttrar sig i tidig barndom som utvecklingsstörningar, krampanfall, svag hudpigmentering, eksem och demyelinering i det centrala nervsystemet.

Engelsk definition

A group of autosomal recessive disorders marked by a deficiency of the hepatic enzyme PHENYLALANINE HYDROXYLASE or less frequently by reduced activity of DIHYDROPTERIDINE REDUCTASE (i.e., atypical phenylketonuria). Classical phenylketonuria is caused by a severe deficiency of phenylalanine hydroxylase and presents in infancy with developmental delay; SEIZURES; skin HYPOPIGMENTATION; ECZEMA; and demyelination in the central nervous system. (From Adams et al., Principles of Neurology, 6th ed, p952).
