Ambry Genetics

Jun 06, 2023

The c.47T>G (p.V16G) alteration is located in exon 1 (coding exon 1) of the DBX2 gene. This alteration results from a T to G substitution at nucleotide position 47, causing the valine (V) at amino acid position 16 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
