Abstract:We describe a novel polymerase chain reaction (PCR) and deoxyribonucleic acid (DNA) sequencingbased assay for rapid genotyping of the polymorphic Sp1 binding site in the COL1A1 gene (1). A single nucleotide G-->T substitution polymorphism at this GC-rich site has recently been reported to be a predictive genetic marker for low bone mineral density (BMD). To simplify screening for this marker, we optimized PCR conditions and subjected the amplicons to pyrosequencing, which is a convenient high-throughput sequen… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
