WebAug 27, 2024 · We identified a deep intronic SNV, rs3874648G> A, located in a conserved binding site of the splicing regulator Tra2-β in PKD1 intron 30. Reverse-transcription PCR (RT-PCR) of peripheral blood leukocytes (PBL) from an ADPKD patient homozygous for rs3874648-A identified an atypical PKD1 splice form. WebApr 7, 2024 · Precursor mRNA (pre-mRNA) splicing is the processing step in the gene expression pathway that involves the removal of intronic sequences and ligation of exonic sequences to form mature RNAs (mRNAs). This process is carried out by the spliceosome, a complex molecular machinery that needs to be re-assembled de novo for every …
