Genes affected

GSDMD (HGNC:25697): (gasdermin D) Gasdermin D is a member of the gasdermin family. Members of this family appear to play a role in regulation of epithelial proliferation. Gasdermin D has been suggested to act as a tumor suppressor. Alternatively spliced transcript variants have been described. [provided by RefSeq, Oct 2009]

Collection Method: clinical testing

The c.309G>T (p.K103N) alteration is located in exon 6 (coding exon 2) of the GSDMD gene. This alteration results from a G to T substitution at nucleotide position 309, causing the lysine (K) at amino acid position 103 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
