Biallelic variants in the non-coding RNA gene RNU4-2 cause a recessive neurodevelopmental syndrome with distinct white matter changes

The paper identifies biallelic variants in RNU4-2 causing a recessive neurodevelopmental syndrome with distinct white matter changes, expanding the known genotypic and phenotypic spectrum of RNU4-2-related disorders.

Dominant variants in major spliceosome U4 and U5 small nuclear RNA genes cause neurodevelopmental disorders through splicing disruption

The paper identifies de novo variants in RNU4-2 and RNU5B-1 as causes of neurodevelopmental disorders by disrupting splicing, with variant location and allele phase influencing clinical severity.

Saturation genome editing of RNU4-2 reveals distinct dominant and recessive neurodevelopmental disorders

This study uses saturation genome editing to analyze RNU4-2 variants, identifying functional impacts and redefining the ReNU syndrome critical region.

Exome sequencing as a first-tier test for copy number variant detection : retrospective evaluation and prospective screening in 2418 cases.

This paper evaluates exome sequencing as an alternative to chromosomal microarray for detecting copy number variants in rare disorders, showing improved diagnostic yield in prospective cases.
