    Moderate nucleotide diversity in the Atlantic herring is associated with a low mutation rate

    Chungang Feng et al.
    The Atlantic herring has the lowest mutation rate yet estimated in a vertebrate species and this partially explains its moderate nucleotide diversity given the large population size.

    A novel twelve class fluctuation test reveals higher than expected mutation rates for influenza A viruses

    Matthew D Pauly et al.
    A new assay for specific mutational classes provides preciseestimates of the mutation rates and mutational bias for influenza A viruses.

    Recurrent gain of function mutation in calcium channel CACNA1H causes early-onset hypertension with primary aldosteronism

    Ute I Scholl et al.
    A novel Mendelian disease featuring early-onset hypertension is caused by a recurrent gain of function mutation in CACNA1H, which encodes the voltage-gated calcium channel Cav3.2.

    Selection on mutators is not frequency-dependent

    Yevgeniy Raynes, Daniel Weinreich
    Contrary to intuition that the evolutionary fate of mutation rate modifying alleles is frequency-dependent, neither the strength nor the sign of selection on modifiers depends on initial frequency.

    Large, three-generation human families reveal post-zygotic mosaicism and variability in germline mutation accumulation

    Thomas A Sasani et al.
    Rates of germline mutation accumulation are highly variable across families of similar genetic ancestry, and post-zygotic mosaicism is a substantial source of de novo mutations.

    Active RNAP pre-initiation sites are highly mutated by cytidine deaminases in yeast, with AID targeting small RNA genes

    Benjamin JM Taylor et al.
    Transcribed promoters are highly susceptible to mutation by cytidine deaminases, implicating stable exposure of single stranded DNA structures, rather than cofactors, in localising mutation during tumourigenesis and antibody maturation.

    A homozygous FANCM mutation underlies a familial case of non-syndromic primary ovarian insufficiency

    Baptiste Fouquet et al.
    Bilallelic mutations of FANCM, a DNA-damage response gene whose heterozygous mutations predispose to breast cancer, are involved in a familial case of Primary Ovarian Insufficiency establishing a link between infertility and cancer.

    Resolving rates of mutation in the brain using single-neuron genomics

    Gilad D Evrony et al.
    The reanalysis of data from a recent study that claimed retrotransposon mutations are ubiquitous in the human brain outlines a general framework for the design and analysis of single-cell genomics studies.
