Variant 20-53253763-A-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_173485.6(TSHZ2):c.305A>G(p.Asp102Gly) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,888 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D102H) has been classified as Uncertain significance.

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.

The c.305A>G (p.D102G) alteration is located in exon 2 (coding exon 2) of the TSHZ2 gene. This alteration results from a A to G substitution at nucleotide position 305, causing the aspartic acid (D) at amino acid position 102 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
