How do transposons jump when they’re released from host control? I babysat two chromosomes for 2 years, making sure they are ok without most piRNAs. Here’s what we found & excited to share my 1st postdoc paper: “piRNA loss unleashes episodic transposition bursts” www.biorxiv.org/content/10.6...
piRNA loss unleashes episodic transposition bursts
In Metazoa, transposon expression is suppressed by the piRNA pathway, and disruption of this pathway leads to rampant transposon expression. However, it remains unclear whether increased transposon ex...

Happy to highlight new findings by Vanesa Getseva and Lin Poyraz about the sources of variation in germline mutation rates among humans: www.biorxiv.org/content/10.6... Joint work with Anastasia Stolyarova and @ipsitaagarwal.bsky.social. 1/n
A sibling study of variation in parental mutation rates
People are born with variable numbers of de novo germline mutations (DNMs), depending primarily on the ages of their parents. To explore additional causes, we developed an approach to call DNMs from nucleotide differences between siblings in genomic regions inherited identical by descent from both parents. Applying it to whole genome sequences from 28,985 sibling pairs of diverse genetic ancestries present in the UK Biobank and All of Us datasets, as well as 2,330 trios, we identified >800K autosomal DNMs and characterized mutation phenotypes in 27,645 sets of parents. We found subtle shifts in the mutation spectrum but no differences in total DNM rates among genetic ancestry groups, or between smokers and non-smokers. Testing for associations between parental mutation phenotypes and their burden of loss-of-function and deleterious missense variants in a set of 180 DNA repair and maintenance genes, we discovered that disruptions in REV1 and LIG1 increase germline mutation rates, and thus that rare mutator alleles segregate in population cohorts. ### Competing Interest Statement The authors have declared no competing interest.
