PTPN3

Overview

PTPN3 encodes a non-receptor protein tyrosine phosphatase. In hepatocellular carcinoma, PTPN3 was identified as a target of recurrent homozygous deletion, suggesting a tumor-suppressor role in liver cancer.

Alterations observed in the corpus

  • In hepatocellular carcinoma (HCC), PTPN3 was identified as a target of recurrent homozygous deletion in the INSERM/TCGA 243-case exome cohort; listed alongside CFH and IRF2 as recurrently homozygously deleted. PMID:25822088

Cancer types (linked)

  • HCC: recurrent homozygous deletion; candidate tumor suppressor in liver cancer. PMID:25822088

Co-occurrence and mutual exclusivity

  • No specific co-occurrence or mutual exclusivity patterns reported in the corpus.

Therapeutic relevance

  • No direct therapeutic relevance established in the corpus.

Open questions

  • Functional role of PTPN3 loss in HCC pathogenesis requires experimental validation.
