Collection Method: clinical testing

The c.59T>A (p.V20D) alteration is located in exon 1 (coding exon 1) of the CLDND2 gene. This alteration results from a T to A substitution at nucleotide position 59, causing the valine (V) at amino acid position 20 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
