Data from Atlas, Mitelman, Cosmic Fusion, Fusion Cancer, TCGA fusion databases with official HUGO symbols (see references in chromosomal bands)
THRA (17q21.1) / GSDMA (17q21.1)
Note GSDMA is the first member of Gasdermin family genes which, with Gadermin-related genes, DFNA5 and DFNB59, form Gasdermin superfamily.


  Genomic organization of the GSDMA gene.
Description 12 exons, spans approximately 13 kb of genomic DNA in the centromere-to-telomere orientation. The translation initiation codon is located to exon 2, and the stop codon to exon 12.
Transcription mRNA of approximately 1.5 kb.
Pseudogene Not reported.


  GSDMA is involved in TGF-beta signaling which regulates apoptosis induction in pit cells of the gastric epithelium. Signaling from TGF-beta receptor up-regulates LMO1, a transcription factor. LMO1 binds to the promoter of GSDMA gene and enhances its expression, that results in the apoptosis induction in the pit cells.
Description The GSDMA gene encodes a 445 amino acid protein with estimated molecular weight of 49377.95 Da. The Gasdermin family proteins have 9 conserved motifs but no known functional motif.
Expression GSDMA protein is expressed in pit cells of the gastric epithelium, where it is involved in maintenance of homeostasis by its apoptosis induction ability under TGF-beta signaling. Its expression was also observed in epithelial cells of the esophagus, skin and mammary gland.
Localisation Cytoplasm.
Function Apoptosis induction, but detail is unknown.
Homology Human genome possesses its three paralogues, GSDMB, GSDMC and GSDMD. Both N- and C-terminal amino acids are conserved among them.


Germinal Not reported.
Somatic Not reported.

Implicated in

Entity Gastric cancer
Note GSDMA gene is frequently silenced in gastric adenocarcinoma (16 in 18 cases examined including both diffuse and intestinal types), whose relation to prognosis is unknown.
Entity Esophageal cancer
Note GSDMA gene is frequently silenced in esophageal squamous cell carcinoma (41 in 42 cases examined).
