Variant ribosomal RNA alleles are conserved and exhibit tissue-specific expression
Science Advances, 2018 Ribosomal RNA sequence variants are conserved, exhibit tissue-specific expression, and are found in actively translating ribosomes. The ribosome, the integration point for protein synthesis in the cell, is conventionally considered a homogeneous ...

Mosaicism in Vacuolating Cytotoxin Alleles of Helicobacter pylori
Journal of Biological Chemistry, 1995 Approximately 50% of Helicobacter pylori strains produce a cytotoxin, encoded by vacA, that induces vacuolation of eukaryotic cells. Analysis of a clinically isolated tox strain (Tx30a) indicated secretion of a 93-kDa product from a 3933-base pair vacA ...

Allele age and a test for selection on rare alleles [PDF]
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000 An approximate expression for the probability distribution of the age of a neutral allele as a function of its frequency is derived for a population undergoing arbitrary changes in population size. A simple maximum–likelihood estimator of allele age based on frequency is also obtained.

Risk alleles for multiple sclerosis identified by a genomewide study.
New England Journal of Medicine, 2007 BACKGROUND Multiple sclerosis has a clinically significant heritable component. We conducted a genomewide association study to identify alleles associated with the risk of multiple sclerosis. METHODS We used DNA microarray technology to identify common
