The intricate interplay between somatic mutations and copy number alterations critically influences tumour evolution and patient prognosis. However, traditional genomic analyses often treat these alterations independently, overlooking gene mutant dosage - a key emergent property of their interaction. Here, we develop an innovative computational framework that infers mutation copy number and multi…

Abstract Erythroid cells require specialized microenvironments called erythroblastic islands (EBIs), niches comprising a central macrophage surrounded by developing erythroid precursors, to complete their maturation. Understanding EBI composition and function has been limited by two-dimensional in vitro models and the unclear composition of EBIs in human hematopoietic tissues. Using spatial trans…

Abstract Peanut ( Arachis hypogaea L.) is a globally significant leguminous oil crop. Here we present telomere-to-telomere genome assemblies for two diploid and four tetraploid peanut varieties, resulting in high-quality reference genomes, showing that the complex activities of transposable elements, chromosomal rearrangements and centromere expansions within subgenomes collectively contribute to…

Polycystic ovary syndrome (PCOS) and its underlying features remain poorly understood. In this genetic study (n = 544,513), we expand the number of genetic loci from 16 to 29, and additionally identify 31 associated plasma proteins. Many risk-increasing loci were associated with later age at menopause, underscoring the reproductive longevity related to an increased oocyte number and/or availabili…

We recently showed that mutations in the snRNA genes RNU4-2 and RNU2-2 are prevalent causes of dominant neurodevelopmental disorders (NDDs). Here, by genetic association, we demonstrate the existence of a recessive form of RNU2-2 syndrome. We inferred a log Bayes factor for a recessive model of association of 18.2. Conditional on that model, 17 rare variants had a posterior probability of pathoge…

Abstract Neurodevelopmental disorders (NDDs) affect 2–4% of the population, are predominantly genetic and remain unsolved in ~50% of individuals. We show that rare biallelic variants in RNU2-2 are enriched and over-transmitted in individuals with unresolved NDDs. We define a recessive RNU2-2 syndrome, delineate its unique genetic architecture and show that it manifests clinically as a severe deve…

Abstract Small nuclear RNAs (snRNAs) are essential components of the spliceosome. De novo variants in snRNA genes RNU4-2 (ReNU syndrome), RNU5B-1 and RNU2-2 have been linked to dominant neurodevelopmental disorders (NDDs), revealing a large unexpected contribution of noncoding RNA genes to genetic diseases. Here, through international collaborations, we analyze systematically 200 potentially func…

Genes & Health (G&H) is a biomedical study of adult British Pakistani and Bangladeshi research volunteers enriched for autozygosity. Here we performed whole-exome sequencing in 44,028 G&H participants, establishing a large publicly available South Asian exome resource linked to longitudinal electronic health records. We performed exome-wide association analyses for 645 electronic health record-de…

The skin is the largest human organ and a site of substantial disease burden, yet its cellular and molecular organization across the body is largely undefined. Here we construct an organ-wide single-cell spatial atlas of ~1.2 million cells from normal adult human skin, resolving the location of 45 cell types across 114 samples encompassing 15 anatomic sites. We uncover site-specific stereotypic c…
