SMYD3

Overview

SMYD3 encodes a histone methyltransferase (SET and MYND domain-containing protein 3) that trimethylates histone H4K20 and H3K4, promoting transcriptional activation. In GBM, SMYD3 has been identified as a focal deletion target, suggesting a potential tumor-suppressive context.

Alterations observed in the corpus

  • Single-gene focal deletion target in GBM; identified alongside LRP1B, NPAS3, and LSAMP as single-gene focal deletion events in the TCGA GBM comprehensive genomic characterization PMID:24120142

Cancer types (linked)

  • GBM — focal deletion target identified in the TCGA GBM comprehensive genomic characterization PMID:24120142

Co-occurrence and mutual exclusivity

  • Co-identified as a single-gene focal deletion target in the same GBM dataset as LRP1B, NPAS3, and LSAMP PMID:24120142

Therapeutic relevance

  • No direct therapeutic targeting reported in the corpus.

Open questions

  • Functional significance of SMYD3 focal deletion in GBM is not established; SMYD3 is paradoxically reported as an oncogene in other tumor types (e.g., colorectal, hepatocellular), making its role in GBM as a deletion target noteworthy and unresolved.
