Genes affected

DACH2 (HGNC:16814): (dachshund family transcription factor 2) This gene is one of two genes which encode a protein similar to the Drosophila protein dachshund, a transcription factor involved in cell fate determination in the eye, limb and genital disc of the fly. The encoded protein contains two characteristic dachshund domains: an N-terminal domain responsible for DNA binding and a C-terminal domain responsible for protein-protein interactions. This gene is located on the X chromosome and is subject to inactivation by DNA methylation. The encoded protein may be involved in regulation of organogenesis and myogenesis, and may play a role in premature ovarian failure. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2008]

Ambry Genetics

Sep 27, 2022

The c.854C>A (p.A285E) alteration is located in exon 5 (coding exon 5) of the DACH2 gene. This alteration results from a C to A substitution at nucleotide position 854, causing the alanine (A) at amino acid position 285 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
