Genes affected

DACT2 (HGNC:21231): (dishevelled binding antagonist of beta catenin 2) Predicted to enable several functions, including beta-catenin binding activity; delta-catenin binding activity; and protein kinase C binding activity. Predicted to be involved in several processes, including epithelial cell morphogenesis; inner medullary collecting duct development; and negative regulation of nodal signaling pathway. Predicted to act upstream of or within hematopoietic progenitor cell differentiation. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

The c.1897A>G (p.R633G) alteration is located in exon 4 (coding exon 4) of the DACT2 gene. This alteration results from a A to G substitution at nucleotide position 1897, causing the arginine (R) at amino acid position 633 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
