WES Analysis of precancerous lesions in Lynch Syndrome

The project focuses on identifying the genetic alterations involved in the early stages of tumor development in individuals with Lynch Syndrome. Using Whole Exome Sequencing (WES), the study aims to characterize somatic mutations and molecular pathways that drive the transformation from normal tissue to precancerous lesions. This research contributes to a better understanding of tumorigenesis in hereditary colorectal cancer syndromes.

EGAD50000002222	This dataset includes whole-exome sequencing data from precancerous colorectal lesions (adenomas and advanced adenomas) obtained from 19 patients with Lynch syndrome. Forty-four samples are analyzed, including 33 mismatch repair–deficient (dMMR) and 11 mismatch repair–proficient (pMMR) lesions as assessed by immunohistochemistry. Library preparation was performed using the Twist Human Core Exome + RefSeq + Mitochondrial Panel, followed by sequencing on the Illumina NovaSeq 6000 platform. Aligned BAM files were generated with the DRAGEN pipeline using the human reference genome hg38	Illumina NovaSeq 6000	44
