Ambry Genetics

Jul 09, 2021

The c.26T>C (p.V9A) alteration is located in exon 1 (coding exon 1) of the PM20D2 gene. This alteration results from a T to C substitution at nucleotide position 26, causing the valine (V) at amino acid position 9 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
