Journal ArticleDOI
Estimating African American admixture proportions by use of population-specific alleles.
Esteban J. Parra,Amy Marcini,Joshua M. Akey,Jeremy J. Martinson,Mark A. Batzer,Richard S. Cooper,Terrence Forrester,David B. Allison,Ranjan Deka,Robert E. Ferrell,Mark D. Shriver +10 more
TL;DR: Significant nonrandom association between two markers located 22 cM apart (FY-null and AT3) is detected, most likely due to admixture linkage disequilibrium created in the interbreeding of the two parental populations, emphasize the importance of admixed populations as a useful resource for mapping traits with different prevalence in two parental population.
Journal ArticleDOI
Relative mutation rates at di-, tri-, and tetranucleotide microsatellite loci
TL;DR: Applying ANOVA to the distributions of the allele sizes at microsatellite loci from a set of populations, grouped by repeat motif types, provides an estimate of motif-type-specific mutation rates up to a multiplicative constant, indicating that the earlier suggestion of higher mutation rates of tetranucleotides in comparison with the din nucleotides may stem from a nonrandom sampling of tetanucleotide loci in direct mutation assays.
Journal ArticleDOI
Genetic and environmental risk factors for intracerebral hemorrhage: preliminary results of a population-based study.
Daniel Woo,Laura Sauerbeck,Brett M. Kissela,Jane Khoury,Jerzy P. Szaflarski,James Gebel,Rakesh Shukla,Arthur M. Pancioli,Edward C. Jauch,Anil G. Menon,Ranjan Deka,Janice Carrozzella,Charles J Moomaw,Robert N. Fontaine,Joseph P. Broderick +14 more
TL;DR: In this paper, the authors report a preplanned, midpoint analysis of the first population-based, case-control study that examines both genetic and environmental risk factors of ICH.
Journal ArticleDOI
Y-Chromosome Evidence for a Northward Migration of Modern Humans into Eastern Asia during the Last Ice Age
Bing Su,Junhua Xiao,Peter A. Underhill,Ranjan Deka,Weiling Zhang,Joshua M. Akey,Wei Huang,Di Shen,Daru Lu,Jingchun Luo,Jiayou Chu,Jiazhen Tan,Peidong Shen,Ronald W. Davis,Luigi Luca Cavalli-Sforza,Ranajit Chakraborty,Momiao Xiong,Ruofu Du,Peter J. Oefner,Zhu Chen,Li Jin,Li Jin +21 more
TL;DR: This pattern indicates that the first settlement of modern humans in eastern Asia occurred in mainland Southeast Asia during the last Ice Age, coinciding with the absence of human fossils in easternAsia, 50,000-100,000 years ago.
Journal Article
Ethnic-affiliation estimation by use of population-specific DNA markers.
Mark D. Shriver,Michael W. Smith,Li Jin,Amy Marcini,Joshua M. Akey,Ranjan Deka,Robert E. Ferrell +6 more
TL;DR: Through a search of the literature and of unpublished data on allele frequencies, a panel of population-specific genetic markers are identified that enable robust ethnic-affiliation estimation for major U.S. resident populations and it is demonstrated that this panel of markers provides significant statistical power for ethnic-Affiliation estimation.
