Identification of 10 white fish species associated with U.K. food products was achieved using PCR−RFLP the mitochondrial cytochrome b gene. Use lab-on-a-chip capillary electrophoresis for end-point analysis enabled accurate sizing DNA fragments and identification at a level 5% (w/w) in admixture. One restriction enzyme, DdeI, allowed discrimination eight species. When combined NlaIII HaeIII, specific profiles all were generated. The method applied to range subjected an interlaboratory study...

Background: The common intronic deletion, MYBPC3 Δ25 , detected in 4% to 8% of South Asian populations, is reported be associated with cardiomyopathy, ≈7-fold increased risk disease variant carriers. Here, we examine the contribution hypertrophic cardiomyopathy (HCM) a large patient cohort. Methods: Sequence data from 2 HCM cohorts (n=5393) was analyzed determine frequency and co-occurrence pathogenic variants genes. Case-control haplotype analyses were performed compare frequencies assess...

As part of a student elective, this pilot study aimed at investigating attitudes and practices concerning gutka use in town India. It was hoped that information gained would assist formulating an appropriate health education programme to encourage cessation locally provide more about habit which is also relevant some UK South Asian populations.124 consecutively attending subjects (103 males 21 females) charity-run dental clinic Chitrakoot, India, were interviewed using semi-structured...

Recent work by Shah and colleagues demonstrated that many variants in the ClinVar database are misclassified, disease-specific allele frequency (AF) thresholds can identify wrongly classified alleles flagging too prevalent population to be causative of rare penetrant disease. While we agree with main conclusions this work, authors compare their AF filtering approach our recently published method, concluding method advanced 9may prone removing potentially pathogenic variants9. This is...
