Abstract
Thank you for visiting naturecom You are using a browser version with limited support for CSS To obtain the best experience we recommend you use a more up to date browser or turn off compatibility mode in Internet Explorer In the meantime to ensure continued support we are displaying the site without styles and JavaScriptWe have developed a fast and comprehensive method to scan for point mutations in a gene on X chromosome A target region of the gene is first amplified Then using the amplified product as a template PCR is carried out with multiple shortlength forward primers arrayed in tandem in the scanned region and a common reverse primer The absence of amplified product defines the site of a mutation within a narrow region of the primer recognition site To evaluate our method point mutations in exon 12 of the human glucose6phosphate dehydrogenase G6PD gene were used as a model system Out of 12 Singaporean G6PDdeficient patients 6 cases were shown by the method to have a nucleotide change in this exon Sequence analysis confirmed the presence of a nucleotide change in the region identified by our scanning Thus our method is accurate in localizing mutations within a narrow region and allows large numbers of samples to be handled simultaneously
