Schematic of SGE library design and CRISPR targeting strategy for RNU4-2
The studies, led by Dr Nicky Whiffin’s team with international collaborators, identified how mutations in RNU4-2 — a small non-coding gene — can cause neurodevelopmental disorders. Published in Nature and Nature Genetics, this work represents a significant step forward in understanding the role of previously overlooked regions of the genome, particularly non-coding sequences that do not produce proteins but play critical roles in gene regulation and cellular function.
These findings further advance understanding of how variation in small non-coding genes can drive human disease, reinforcing the growing importance of this previously underexplored part of the genome. Together, they highlight the power of genomic technologies to uncover hidden causes of disease and have important implications for patients and families. By enabling more accurate genetic diagnoses, they pave the way for improved clinical care and future therapeutic development.
Alongside these studies, Nicky also contributed to related work on RNU2-2, published in Nature Genetics, which identified mutations in another small non-coding gene as a cause of neurodevelopmental disorders.
The findings also underscore Oxford’s leading role in genomic medicine and collaborative research tackling complex genetic conditions.
