Welcome to the Pemberton Lab...

Quoted in CBC Article

Trevor Pemberton was recently interviewed by CBC for an article reporting the findings of Sanjak and Colleagues who show that a wide variety of human traits are subject to ongoing natural selection, and that this relationship varies in strength but not direction between males and females. These findings provide important new insights into how in the contemporary human phenotype has been shaped by natural selection.

Publication in BMC Genomics

Our recent study entitled "Weighted likelihood inference of genomic autozygosity patterns in dense genotype data" has just been published in BMC Genomics. In this article, we report a new method for inferring genomic regions of autozygosity (ROA) in dense genotype data and highlight its performance and unique properties using The 1000 Genomes Project Phase 3 data.

Publication in Current Biology

Our recent study entitled "Parallel trajectories of genetic and linguistic admixture in a genetically admixed creole population" has just been published in Current Biology. In this article, we report the first investigation of gene-language correlations at the individual/ideolectal level, showing that Cape Verdean genetic and linguistic admixture have followed parallel evolutionary trajectories.

Publication in PNAS

Our study entitled "Linkage disequilibrium matches forensic genetic records to disjoint genomic marker sets" has just been published in PNAS. In this article, we show how records in microsatellite databases, such as those used by law enforcement agencies, and single-nucleotide variant databases, such as those maintained by personal genomics companies, that represent the same person can be identified with high accuracy.

Publication in Bioinformatics

We have published a software tool called GARLIC for calling and classifying runs of homozygosity (ROH) in genome-wide SNP genotype data in the popular TPED/TFAM format based upon the methods of Pemberton et al. (2012). This software will facilitate the accurate inference and classification of ROH in large-scale genotype data sets created by furture population- and disease-genetic studies.

About the Lab

Research in the lab is focused on understanding the genetic etiology of Mendelian and complex traits, how human population history and cultural practices influence patterns of genetic variation, and the ways in which these patterns can be harnessed to advance the discovery of genes that underlie human disease. We are more broadly interested in understanding how the geographic distribution of human genetic variation relates to the susceptibility of different populations to disease, and ultimately how this variation in disease susceptibility reflects the evolutionary history of human populations. Our efforts will provide a foundation for the development of diagnostic and therapeutic strategies that will help reduce the disease-burden of diverse populations.

Current Research Projects

Phenotype Mapping

The identification of novel genes and genetic variants underlying Mendelian and complex phenotypes is a necessary step in furthering our understanding of their underlying processes and human development. For disease phenotypes, such an understanding is a fundamental step toward developing novel diagnostic and therapeutic strategies to help reduce the disease-burden of diverse populations.

Cystic Kidney Disease

The identification and characterization of a novel modifier gene of polycystic kidney disease in the Han:SPRD-Cy rat model. Our findings will form the foundation for the development of better treatments that can reduce patient suffering and the burden polycystic kidney disease places on healthcare and transplant systems worldwide.

Genomic Homozygosity

Genome-wide patterns of runs of homozygosity and their variation across individuals can provide a rich source of data for uncovering patterns of diversity, population structure, and history of human populations, and for facilitating the identification of genes underlying recessive traits via homozygosity mapping.

Genetics of Asian Indians

In India, centuries-old marriage customs have introduced extensive social structuring into the contemporary population, potentially with significant consequences for genetic variation. Understanding the genetic landscape in India is a necessary first step toward identifying the genetic factors that underlie diseases such as cardiovascular disease and diabetes that occur at high frequency in Asian Indians.

Genetics of African Pygmies

African Pygmies are hunter-gatherer populations from the equatorial rainforest that have the shortest average adult height among worldwide human populations. Investigating patterns of genetic variation in these populations will hopefully shed light on the biological basis and the putative adaptive role of the short stature of Pygmy populations, and increase our understanding of their unique evolutionary history.

Genetics of Cape Verde

Cape Verde is an archipelago consisting of nine inhabited islands located off the shores of Senegal whose contemporary populations reflect the diverse cultural and ethnic backgrounds of the original 15th century European and continental African settlers. Thus, the Cape Verde archipelago affords us an opportunity to jointly reconstruct the history of both language varieties and genetic diversity in an admixed population.
