SF3B1 splicing signature

We describe individuals with de novo pathogenic variants in SF3B1. SF3B1 is a core component of the U2 snRNP complex that ensures accurate branchpoint and 3′ splice-site recognition, and its mutations induce aberrant splicing that contributes to tumorigenesis, notably in myelodysplastic syndromes. We aim to study splicing defects associated with constitutional pathogenic variants.

EGAD50000002121	This dataset includes exome-captured RNA-Seq made with exome v8 (Agilent) - library preparation on a MAGNIS XT-HS2 starting from 100ng of RNA. RNA has been extracted from lymphocytes cultures from 2 probands with SF3B1 mutations and 14 controls. All 16 RNA-Seq were sequenced on a single HighOutput flowcell 2x75bp (NextSeq550). Raw fastq files have between 20 and 30M paired-reads.	NextSeq 550	16
