title: [Phenotypic expression of Lp(a) in Spanish children and adolescents].
abstract: BACKGROUND
  To know the distribution of phenotypes Lp(a) in an young population.
  
  
  METHODS
  Lipoprotein levels, lipoprotein(a), apolipoproteins and the Lp(a) phenotypes were determined in 105 children, selected according to their cholesterol concentrations.
  
  
  RESULTS
  The Lp(a) concentrations were significantly higher in group with low molecular weight respect to group with high molecular weight. The most frequent isoform was S3.
  
  
  CONCLUSIONS
  The Lp(a) concentrations correlate inversely with the molecular weight of Apo(a) isoforms.
