On April 8th 2024, Chen et al published the identification of variants in a non-coding RNA (RNU4-2) which remarkably explained the diagnosis of approximately ~0.5% of all undiagnosed individuals with neurodevelopmental disorders (NDD). The authors initially identified a recurrent variant (GRCh38:chr12:120,291,839:T:TA; n.64_65insT) in 46 individuals in the Genomics England (GEL) cohort. The variant was not found in any other GEL cohorts (NDD with an existing genetic diagnosis, non-NDD cases, or unaffected individuals). The authors further investigated the phenotypes of Individuals with the variant and showed that there was an enrichment of developmental delay, delayed gross motor development, microcephaly, delayed fine motor development hypotonia, short stature, drooling and absent speech. Expanding analysis to a highly constrained 18bp region of the gene (chr12:120,291,825-120,291,842) and additional NDD cohorts identified a total of 119 individuals with variants in this region, 77.3% of which have n.64_65insT. This variant was observed once in the UK Biobank, in an individual with ‘personal history of disease of the nervous stem and sense organs’. 

 

Using the Geneyx Analysis platform doctors from Hadassah Medical Centre were able to easily search their cohort of 365 genomes to identify a case with this variant, taking only 0.5 minutes and less than a day after the paper was published. The case had phenotype intellectual disability, seizures, and microcephaly and was previously undiagnosed.  

 

The ‘Variant Browser feature of Geneyx Analysis, enables users to search via a graphical user interface for specific regions across their cohort of data, without relying on the skills of a bioinformatician. This can expedite case identification and resolution of unsolved cases.  

The Geneyx Analysis CE-IVD platform has several other features to support users make the most of genome sequencing, including in non-coding regions. 

 

Smart filter – include all variants in the genome at a defined frequency and CADD score, regardless of whether in a coding region.  

Modifier – capture in your analysis all regulatory elements outside of coding regions. It ensures that elements, such as enhancers or promoters, are considered during the analysis. 

Focused analysis – generate a sub-analysis, for example focused only on non-coding regions, to stratify your workflow 

Benefit from enhancers scores such as  

Enhancers (ENHS): The number of enhancers impacted by the event. 

ENH SCORE: Enhancer confidence score. 

ENH-GENE SCORE: Gene-Enhancer associated score.
