BACKGROUND: To know the distribution of phenotypes Lp(a) in an young popula
tion.
METHODS: Lipoprotein levels, lipoprotein(a), apolipoproteins and the Lp(a)
phenotypes were determinated in 105 children, selected according to their c
holesterol concentrations.
RESULTS: The Lp(a) concentrations were significantly higher in group with l
ow molecular weight respect to group with high molecular weight. The most f
requent isoform was S3.
CONCLUSIONS: The Lp(a) concentrations correlate inversely with the molecula
r weight of Apo(a) isoforms.
