Ambry Genetics

Apr 17, 2024

The c.401A>G (p.N134S) alteration is located in exon 4 (coding exon 3) of the TCEANC2 gene. This alteration results from a A to G substitution at nucleotide position 401, causing the asparagine (N) at amino acid position 134 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
