Ambry Genetics

Apr 27, 2024

The c.2021A>T (p.N674I) alteration is located in exon 1 (coding exon 1) of the CTAGE4 gene. This alteration results from a A to T substitution at nucleotide position 2021, causing the asparagine (N) at amino acid position 674 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
