Ambry Genetics

Nov 30, 2022

The c.386C>T (p.A129V) alteration is located in exon 3 (coding exon 3) of the TEX40 gene. This alteration results from a C to T substitution at nucleotide position 386, causing the alanine (A) at amino acid position 129 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
