Short Communication Genotype Analysis Using Human Hair Shaft
نویسندگان
چکیده
Analysis of genotypes for genetic predisposition of diseases has profound and widespread clinical application and has become a fundamental tool in the study of molecular epidemiology. In this study, we report a convenient and completely noninvasive approach to perform genotyping using terminal cephalic hair shaft. The average and median DNA amounts purified from the hair shaft are 112 180 (1 SD) pg/mg and 66 pg/mg of hair shaft, respectively. Using hybridization with molecular beacons that can reliably distinguish single nucleotide polymorphisms at different alleles, we are able to analyze the genotypes of APO-E and G-protein 3 (GNB3) subunit C825T loci in DNA samples obtained from hair shaft in a high throughput format. The amount of DNA obtained from 20 mg of hair shaft is sufficient for multiple independent genotyping assays. These findings demonstrate that terminal hair shaft provides a convenient and reliable genomic DNA source for an analysis of genotypes.

متن کاملHair Shaft Abnormality in Children: a Narrative Review
Background Hair is an ectodermal structure, and its formation is regulated by master genes important in embryology. Hair shaft consists of three major regions: the medulla, cortex and cuticle. Hair shaft abnormality will divide structural hair abnormalities into two broad categories - those associated with increased hair fragility and those not associated with increased hair fragility. We condu...
متن کاملSHORT COMMUNICATION Scopulate hairs in male Liphistius spiders: probable contact chemoreceptors
Adult male Liphistius have dense hair pads on the ventral side of their tarsi. At first glance they appear like the adhesive scopulae, which are well known from mygalomorph spiders. However, a fine structural analysis of these scopulate hairs shows that they lack the brush-like structure with tiny ‘‘endfeet’’ that is typical for such adhesive hairs. Instead, the smooth hair shaft exhibits a sma...
متن کاملThe Post-Apoptotic Fate of RNAs Identified Through High-Throughput Sequencing of Human Hair
The hair of all mammals consists of terminally differentiated cells that undergo a specialized form of apoptosis called cornification. While DNA is destroyed during cornification, the extent to which RNA is lost is unknown. Here we find that multiple types of RNA are incompletely degraded after hair shaft formation in both mouse and human. Notably, mRNAs and short regulatory microRNAs (miRNAs) ...

L. Rudnicka et al. (eds.), Atlas of Trichoscopy, DOI 10.1007/978-1-4471-4486-1_2, © Springer-Verlag London 2012 Most hairs viewed on trichoscopy are normal terminal hairs that are more than 55 m m wide and are uniform in thickness and color [ 1, 2 ] . Hair shaft thickness may be roughly estimated with a handheld dermoscope (thin, normal, thick). Many videodermoscopes include software allowing a...
