Collection Method: clinical testing

The c.17A>T (p.D6V) alteration is located in exon 2 (coding exon 2) of the ZNF326 gene. This alteration results from a A to T substitution at nucleotide position 17, causing the aspartic acid (D) at amino acid position 6 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
