Ambry Genetics

Feb 17, 2022

The c.173A>T (p.D58V) alteration is located in exon 4 (coding exon 3) of the BDH2 gene. This alteration results from a A to T substitution at nucleotide position 173, causing the aspartic acid (D) at amino acid position 58 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
