Supplementary Figure 19 from Tumor Suppressor Genes with Segmental Duplications Are Prone to Somatic Deletions and Structural Variations

Key Points

Tumor suppressor genes with segmental duplications are more susceptible to somatic deletions and structural variations.
A meta-analysis was conducted on a Chinese cohort, focusing on somatic alterations in TSGs before and after size-matching.
The findings indicate a significant relationship between segmental duplications and the frequency of somatic alterations in TSGs.
Understanding these vulnerabilities can aid in developing targeted therapies for cancers featuring such genetic alterations.
