Genetic Variant DACH1:p.Gly81_Ser82insGlyGlyGlyGlyGlyGlyGlyGly (chr13-71866526-T-TGCCGCCGCCGCCGCCGCCGCCGCC) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP3

The NM_080759.6(DACH1):c.220_243dupGGCGGCGGCGGCGGCGGCGGCGGC(p.Gly81_Ser82insGlyGlyGlyGlyGlyGlyGlyGly) variant causes a conservative inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000162 in 1,233,852 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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]
