Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.11C>G (p.A4G) alteration is located in exon 1 (coding exon 1) of the DACT3 gene. This alteration results from a C to G substitution at nucleotide position 11, causing the alanine (A) at amino acid position 4 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
