Human intronless disease associated genes are slowly evolving.
In the present study we have examined human-mouse homologous intronless disease and non-disease genes alongside their extent of sequence conservation, tissue expression, domain and gene ontology composition to get an idea regarding evolutionary and functional attributes. We show that selection has significantly discriminated between the two groups and the disease associated genes in particular ...
متن کاملThe Roles and Evolutionary Patterns of Intronless Genes in Deuterostomes
Genes without introns are a characteristic feature of prokaryotes, but there are still a number of intronless genes in eukaryotes. To study these eukaryotic genes that have prokaryotic architecture could help to understand the evolutionary patterns of related genes and genomes. Our analyses revealed a number of intronless genes that reside in 6 deuterostomes (sea urchin, sea squirt, zebrafish, ...
متن کاملP30: Are There Anxious Genes?
Anxiety comprises many clinical descriptions and phenotypes. A genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. Extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-HT) transporter (5-HTT) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. Complete genome-wide linkage s...
متن کاملSingle Nucleotide Polymorphism Analysis of Protamine Genes in Infertile Men
Background Single nucleotide polymorphism (SNPs) are considered as one of the underlying causes of male infertility. Proper sperm chromatin packaging which involves replacement of histones with protamines has profound effect on male fertility. Over 20 SNPs have been reported for the protamine 1 and 2. MaterialsAndMethods The aim of this study was to evaluate the frequency of two previously repo...
متن کاملChicken /3-Globin Genes
We reported previously that DNA bend sites appear in the human /3-globin locus at an average distance of 680 bp. The relative locations of the sites were conserved among the five active /3-like globin genes and one pseudogene. Here, we mapped the sites in the /3-like globin genes from various species and examined their conservation. The locations of the bend sites in the bovine, rabbit and chic...
