Genes affected

DACT1 (HGNC:17748): (dishevelled binding antagonist of beta catenin 1) The protein encoded by this gene belongs to the dapper family, characterized by the presence of PDZ-binding motif at the C-terminus. It interacts with, and positively regulates dishevelled-mediated signaling pathways during development. Depletion of this mRNA from xenopus embryos resulted in loss of notochord and head structures, and mice lacking this gene died shortly after birth from severe posterior malformations. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2012]

Collection Method: clinical testing

The c.2146C>T (p.P716S) alteration is located in exon 4 (coding exon 4) of the DACT1 gene. This alteration results from a C to T substitution at nucleotide position 2146, causing the proline (P) at amino acid position 716 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
