Genes affected

LZTS2 (HGNC:29381): (leucine zipper tumor suppressor 2) The protein encoded by this gene belongs to the leucine zipper tumor suppressor family of proteins, which function in transcription regulation and cell cycle control. This family member can repress beta-catenin-mediated transcriptional activation and is a negative regulator of the Wnt signaling pathway. It negatively regulates microtubule severing at centrosomes, and is necessary for central spindle formation and cytokinesis completion. It is implicated in cancer, where it may inhibit cell proliferation and decrease susceptibility to tumor development. Alternative splicing of this gene results in multiple transcript variants.

Sep 16, 2021

The c.895C>T (p.R299W) alteration is located in exon 3 (coding exon 2) of the LZTS2 gene. This alteration results from a C to T substitution at nucleotide position 895, causing the arginine (R) at amino acid position 299 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
