Neurodevelopment requires complex spatiotemporal nuclear ribonucleoproteins (snRNPs), and additional expression, which heavily relies on proper RNA splicing. The trans-acting proteins. The conformation and compospliceosome is a ribonucleoprotein complex that removes sition of the spliceosome are ever-changing, which introns from pre-mRNA, joins exons, and produces mature enables flexibility, yet makes it challenging to mRNA. Pathogenic variants in genes that code for spliceosome study [1–4].RNAs and proteins cause RNA mis-splicing and spliceosomopathies. Splicing defects during nervous system In eukaryotic splicing, genes are transcribed as predevelopment upend the tightly controlled neurodevelopmental mRNAs, which become mature mRNAs once the introns process, leading to neurodevelopmental disorders (NDDs). are removed and the exons are joined. Some exons are Despite the fact that the spliceosome is expressed in every cell, present in every mRNA from a given gene, known as not all spliceosomopathies present as NDDs; constitutive splicing, while others are only in some, spliceosomopathies are often tissue-specific in that a variant known as alternative splicing [1]. Splicing assembly for has a greater impact on certain cell lineages or cell types. Here RNA recognition and catalysis is an ordered and cowe discuss spliceosomopathies whose presentations include ordinated process: spliceosomal snRNPs and additional NDDs and focus on spliceosome-coding genes.splicing factors interact in a specific sequence. In eukaryotes, there are two types of spliceosomes: major, U2- Addressesdependent spliceosome and minor, U12-dependent 1 Raymond G.
