Pathogenicity of NUSAP1 Variants Is Defined by NMD-Escape: Evidence From Two Novel Cases and Systematic Population-Based Variant Analysis.
Protein-truncating variants in the 3' region of a transcript, evading mRNA degradation and giving rise to aberrant truncated proteins, are an underrecognized cause in Mendelian diseases. Here, we report two individuals with heterozygous de novo nonsense variants in the penultimate and last exon of NUSAP1, both presenti...
