Ambry Genetics

Dec 09, 2024

The c.40G>A (p.A14T) alteration is located in exon 2 (coding exon 1) of the BDH2 gene. This alteration results from a G to A substitution at nucleotide position 40, causing the alanine (A) at amino acid position 14 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
