A novel SNaPshot assay to detect genetic mutations related to iron metabolism

The minisequencing method is a cost-effective tool to study single-nucleotide polymorphisms in human disease. For this reason, a novel polymerase chain reaction multiplex SNaPshot reaction has been developed that targets 10 autosomal mutations in genes, or regions near to them, reported to be involved in iron metabolism: TMPRSS6, TF, and HFE. To validate this multiplex, 284 samples from unrelated women from the Spanish population were tested at a fertile age. The novel polymerase chain reaction multiplex SNaPshot reaction developed is a very simple, sensitive, and low-cost approach, and therefore will be useful as a tool of clinic diagnosis in iron metabolism alterations and to replicate results obtained from genome-wide linkage analysis.
