Pentanucleotide TTTTA and G/A -914 DNA polymorphisms in apolipoprotein(a) promoter: genotyping by single-tube PCR.

摘要

It is known that pentanucleotide repeat polymorphism, consisting of varying number of (TTTTA) repeats in a promoter, is associated with plasma lipoprotein(a) levels. G/A -914 base substitution has also been correlated with pentanucleotide repeat polymorphism in individuals with high and low lipoprotein(a) levels. To facilitate future analysis of these polymorphisms we have developed a quick and reliable assay for the detection of both polymorphisms in a single polymerase chain reaction.
