Large scale genotype-phenotype correlation analysis based on phylogenetic trees
نویسندگان
چکیده
We provide two methods for identifying changes in genotype that are correlated with changes in a phenotype implied by phylogenetic trees. The first method, VENN, works when the number of branches over which the change occurred are modest. VENN looks for genetic changes that are completely penetrant with phenotype changes on a tree. The second method, CCTSWEEP, allows for a partial matching between changes in phenotypes and genotypes and provides a score for each change using Maddison's concentrated changes test. The mutations that are highly correlated with phenotypic change can be ranked by score. We use these methods to find SNPs correlated with resistance to Bacillus anthracis in inbred mouse strains. Our findings are consistent with the current biological literature, and also suggest potential novel candidate genes.

متن کاملGenotype and phenotype of COVID-19: Their roles in pathogenesis
COVID-19 is a novel coronavirus with an outbreak of unusual viral pneumonia in Wuhan, China, and then pandemic. Based on its phylogenetic relationships and genomic structures the COVID-19 belongs to genera Betacoronavirus. Human Betacoronaviruses (SARS-CoV-2, SARS-CoV, and MERS-CoV) have many similarities, but also have differences in their genomic and phenotypic structure that can influence th...
متن کاملGenotype–Phenotype Correlations in Iranian Myotonic Dystrophy Type I Patients
Objectives: Myotonic Dystrophy type I (DM1) is a dominantly inherited disorder with a multisystemic pattern affecting skeletal muscle, heart, eye, endocrine and central nervous system. DM1 is associated with the expansion and instability of CTG repeat in the 3chr('39') untranslated region of the myotonic dystrophy protein kinase (DMPK) gene located on chromosome 19q13.3. The aim of this study w...
متن کاملA Solution for Universal Classification of Species Based on Genomic DNA
Traditionally, organisms have been classified on the basis of their phenotype. Recently, genotype-based classification has become possible through the development of sequencing technology. However, it is still difficult to apply sequencing approaches to the analysis of a large number of species due to the cost and labor. In most biological fields, the analysis of complex systems comprising vari...
متن کاملSequence and Phylogenetic Analysis of Membrane (M) Gene of Infectious Bronchitis Viruses Isolated in Iran during 2014 - 2015
Background and Aims: Avian infectious bronchitis virus (IBV) has a worldwide distribution and mutations occurring in the large viral genome of IBV have led to extensive antigenic variations among IBVs. This is the first study conducted to determine the complete membrane (M) gene sequences of different Iranian IBV genotypes. Materials and Methods: The M gene of three 793/B (IBKG1,6,7), one Mass...
