Genes affected

DACH1 (HGNC:2663): (dachshund family transcription factor 1) This gene encodes a chromatin-associated protein that associates with other DNA-binding transcription factors to regulate gene expression and cell fate determination during development. The protein contains a Ski domain that is highly conserved from Drosophila to human. Expression of this gene is lost in some forms of metastatic cancer, and is correlated with poor prognosis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.27283418).

The c.1018A>G (p.I340V) alteration is located in exon 3 (coding exon 3) of the DACH1 gene. This alteration results from a A to G substitution at nucleotide position 1018, causing the isoleucine (I) at amino acid position 340 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
