Human genes are not continuous but rather consist of short cod(cid:173) ing regions (exons) interspersed with highly variable non-coding regions (introns). We apply HMMs to the problem of modeling ex(cid:173) ons, introns and detecting splice sites in the human genome. Our most interesting result so far is the detection of particular oscilla(cid:173) tory patterns, with a minimal period ofroughly 10 nucleotides, that seem to be characteristic of exon regions and may have significant biological implications.

Over the next decade, more than a million eukaryotic species are expected to be fully sequenced. This has the potential to improve our understanding of genotype and phenotype crosstalk, gene function and interactions, and answer evolutionary questions. Here, we develop a machine-learning approach for utilizing phylogenetic profiles across 1154 eukaryotic species. This method integrates co-evolution across eukaryotic clades to predict functional interactions between human genes and the context for these interactions. We benchmark our approach showing a 14% performance increase (auROC) compared to previous methods. Using this approach, we predict functional annotations for less studied genes. We focus on DNA repair and verify that 9 of the top 50 predicted genes have been identified elsewhere, with others previously prioritized by high-throughput screens. Overall, our approach enables better annotation of function and functional interactions and facilitates the understanding of evolutionary processes underlying co-evolution.

With the rise in number of eukaryotic species being fully sequenced, large scale phylogenetic profiling can give insights on gene function, Here, the authors describe a machine-learning approach that integrates co-evolution across eukaryotic clades to predict gene function and functional interactions among human genes.

GO has been diagnostics and drug discovery. In this paper, we further extensively used to compute the similarity between genes our previous study on gene-disease relationship (details in section 3) [19, 20]. In this work, we use the specifically with the multifunctional genes. We investigate functional annotations of a gene from the Gene Ontology the multifunctional gene-disease relationship based on the Annotation (GOA) databases to compute the shortest published molecular function annotations of genes from distance (path length) between the Molecular Function the Gene Ontology which is the most comprehensive (mf) GO terms annotating the gene.

Neanderthals are still affecting what illnesses some people develop, how tall they are and how their immune systems work, despite being extinct for 40,000 years. This is thanks to the Neanderthal DNA those of non-African descent inherited from ancestors who mated with our cousins some 50,000 years ago. A study has now revealed how this genetic legacy is still controlling how some people's genes work, with possible consequences for their health. Tellingly, the Neanderthal influence has waned fastest in parts of the body that evolved most rapidly around that time, especially the brain. It suggests that once our direct human ancestors had evolved the equipment for sophisticated language and problem-solving, mating with Neanderthals – and the DNA that came with it – rapidly fell out of fashion.
