Genes affected
TSHZ2 (HGNC:13010): (teashirt zinc finger homeobox 2) This gene is a member of the teashirt C2H2-type zinc-finger protein family of transcription factors. This gene encodes a protein with five C2H2-type zinc fingers, a homeobox DNA-binding domain and a coiled-coil domain. This nuclear protein is predicted to act as a transcriptional repressor. This gene is thought to play a role in the development and progression of breast and other types of cancer. Alternative splicing results in multiple transcript variants encoding different isoforms.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.758C>T (p.T253M) alteration is located in exon 2 (coding exon 2) of the TSHZ2 gene. This alteration results from a C to T substitution at nucleotide position 758, causing the threonine (T) at amino acid position 253 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
