Abstract Reanalysis of genomic data in rare disease is highly effective in increasing diagnostic yields but remains limited by manual approaches. Automation and optimization for high specificity will be necessary to ensure scalability, adoption and sustainability of iterative reanalysis.

Abstract Recently, de novo variants in an 18-nucleotide region in the centre of RNU4-2 were shown to cause ReNU syndrome, a syndromic neurodevelopmental disorder that is predicted to affect tens of thousands of individuals worldwide1,2. RNU4-2 is a non-protein-coding gene that is transcribed into the U4 small nuclear RNA component of the major spliceosome3. ReNU syndrome variants disrupt spliceosome function and alter 5′ splice site selection1,4.

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 developmental and epileptic encephalopathy.

PKD1 5’UTR variants are a rare cause of disease in ADPKD and suggest a new focus for therapeutic development - European Journal of Human Genetics

By John Sayer, Rocio Rius, Andrew Mallett
| Nature Verified
Abstract Autosomal Dominant Polycystic Kidney Disease (ADPKD), caused by pathogenic variants in PKD1 and PKD2, is the most common monogenic cause of kidney failure. Approximately 10% of ADPKD patients remain undiagnosed after coding-region focused genomic testing. Non-coding variants in regulatory regions are not an established cause of disease in ADPKD.

Abstract The major spliceosome contains five small nuclear RNAs (snRNAs; U1, U2, U4, U5 and U6) essential for splicing. Variants in RNU4-2, encoding U4, cause a neurodevelopmental disorder called ReNU syndrome. We investigated de novo variants in 50 snRNA-encoding genes in a French cohort of 23,649 individuals with rare disorders and gathered additional cases through international collaborations.

Abstract Around 60% of individuals with neurodevelopmental disorders (NDD) remain undiagnosed after comprehensive genetic testing, primarily of protein-coding genes1. Large genome-sequenced cohorts are improving our ability to discover new diagnoses in the non-coding genome. Here we identify the non-coding RNA RNU4-2 as a syndromic NDD gene. RNU4-2 encodes the U4 small nuclear RNA (snRNA), which is a critical component of the U4/U6.U5 tri-snRNP complex of the major spliceosome2.

Abstract Mutations in the mitochondrial or nuclear genomes are associated with a diverse group of human disorders characterized by impaired mitochondrial respiration. Within this group, an increasing number of mutations have been identified in nuclear genes involved in mitochondrial RNA biology. The TEFM gene encodes the mitochondrial transcription elongation factor responsible for enhancing the processivity of mitochondrial RNA polymerase, POLRMT.
