Supplementary Figure 21 from Tumor Suppressor Genes with Segmental Duplications Are Prone to Somatic Deletions and Structural Variations

Key Points

MAIN FINDING: There is no significant difference in structural variations between tumor suppressor genes with segmental duplications and those without.
KEY EVIDENCE: Ionizing radiation-induced structural variations were consistent across normal human cell colonies regardless of segmental duplications.
APPROACH: The study utilized normal human cell colonies to examine the effects of ionizing radiation on different gene types.
SIGNIFICANCE: Understanding the role of segmental duplications in tumor suppressor genes may help clarify their vulnerability to genetic changes.

Answers are grounded in this paper and cite their sources.

Analysis reveals no difference in structural variations in genes with or without segmental duplications after ionizing radiation exposure.

No significant difference in ionizing radiation-induced SV between with SDs and without SDs genes across normal human cell colonies.
