Ambry Genetics

Feb 27, 2023

The c.613A>G (p.N205D) alteration is located in exon 7 (coding exon 7) of the TCEA1 gene. This alteration results from a A to G substitution at nucleotide position 613, causing the asparagine (N) at amino acid position 205 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
