Targeted MIP sequencing for healthy samples
We developed Del-Read, an algorithm targeting medium-sized deletions (6-100 BPs) in short-reads, which are challenging for current variant callers relying on alignment. Our focus was on Micro-Homology mediated End Joining deletions (MMEJ-dels), prevalent in myeloid malignancies. MMEJ-dels follow a distinct pattern, occurring between two homologies, allowing us to generate a comprehensive list of MMEJ-dels in the exome. Using Del-Read, we identified numerous novel germline and somatic MMEJ-dels in Beat AML and TCGA-breast datasets. Validation in 500 healthy individuals confirmed their presence.
