Roulette enables the estimation of germline mutation rates at basepair resolution from humans. Genes encoding small nuclear RNA showed significant deviations from the mutation rate predicted by Roulette, highlighting RNA polymerase III (Pol III)-dependent transcription as a potent source of mutations in the human genome.
A test of four genomic sequence-to-expression deep learning models (Enformer, Basenji2, ExPecto, Xpresso) finds that they often fail to predict the correct direction of effect of cis-regulatory genetic variation on gene expression.
The chemotherapeutic agent CX-5461 is shown to be a potent mutagen in hTERT-RPE1, HAP1 and human induced pluripotent stem cells. The compound generates distinct mutational patterns of single- and double-base substitutions, as well as of small insertions and deletions, that were detectable following a single exposure.
scHLApers is an analysis pipeline that quantifies single-cell expression of HLA genes using a personalized genomic reference. Mapping of HLA expression quantitative trait loci at single-cell resolution identifies dynamic effects across cell states.
A multivariate framework for isoform-resolution transcriptome-wide association studies enables modeling of a greater number of genes, with the benefit of identifying isoform-specific associations with psychiatric traits not observed at the gene level.
Genome-wide analyses yield insights into the polygenic effects contributing to clinical heterogeneity in attention deficit hyperactivity disorder, advancing understanding of its genetic etiology and serving as a model for future studies in other complex disorders.
Multi-ancestry genome-wide association meta-analyses identify risk loci for cannabis use disorder. Genomic structural equation modeling and genetic correlation analyses show overlap with several other traits, including impulsivity and psychopathology.
Phenotype imputation increases the effective sample size of major depressive disorder cases in UK Biobank, enhancing study power and polygenic risk score (PRS) accuracy. A new pleiotropy metric enables assessment of PRS specificity and comparison among different PRS models.
AutoComplete is a deep learning-based method that imputes missing phenotypes in population-scale biobank datasets, increasing effective sample sizes and improving power for genetic discoveries in genome-wide association studies.
Loss-of-function mutations in primate-specific ZNF808 cause pancreatic agenesis. Mechanistically, the loss of ZNF808 leads to the activation of the MER11 family of transposable elements in a regulatory capacity that ultimately induces a liver-specific program of gene expression during pancreatic differentiation.
In pancreatic duct adenocarcinoma, super-enhancer RNAs (seRNAs) have higher N6-methyladenosine (m6A) levels than in adjacent normal tissue due to upregulation of the METTL3 cofactor CFL1. Aberrant m6A seRNAs promote oncogene expression via the YTHDC2–MLL1 complex.
Circular extrachromosomal DNA in high-risk medulloblastoma contributes to tumor heterogeneity and associates with relapse and survival. Enhancer rewiring events involving known oncogenes are frequent events, affecting transcription and proliferation.
CRISPR activation/interference screens identify transcriptional regulators of human CD8+ T cells, including BATF3. BATF3 overexpression counteracts T cell exhaustion and enhances cancer immunotherapy in in vivo models.
JaBbA v1 pinpoints the ‘loose ends’ of large (>10-kb) unmapped structural variants in short-read DNA sequencing, suggesting that about 90% of cancer chromosomal alterations outside centromeres are resolvable with short reads and that long reads will primarily improve calling of smaller somatic variants.
A multi-ancestry genome-wide association study of prostate cancer performed in 156,319 cases and 788,443 controls identifies 187 novel risk variants associated with the disease. Genetic risk scores associated with overall risk, and risk of aggressive disease in men of African ancestry.
A barcode-based approach applied to UK Biobank and an Icelandic cohort identifies drivers of clonal hematopoiesis (CH) and finds associations between CH and multiple diseases. Genome-wide association analyses identify 25 loci associated with CH susceptibility.
Chromosome-level genome assemblies of three Allium crops (onion, garlic and Welsh onion) and spatial RNA sequencing provide insights into Allium trait evolution and gene expression patterns during onion bulb formation.
Homozygous loss-of-function variants in phospholipase A/acyltransferase 3 (PLAAT3) underlie a new lipodystrophy syndrome. Functional studies link PLAAT3 loss with peroxisome proliferator-activated receptor gamma (PPARγ)-mediated defects in white adipose tissue differentiation and function.
Single-haplotype genome assemblies from five cat species shed light on the dynamics of structural variations during felid radiation and resolve sensory gene repertoires associated with adaptation and domestication.
