Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.155T>C (p.M52T) alteration is located in exon 1 (coding exon 1) of the DACT3 gene. This alteration results from a T to C substitution at nucleotide position 155, causing the methionine (M) at amino acid position 52 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
