Ambry Genetics

Oct 08, 2024

The c.970T>C (p.C324R) alteration is located in exon 9 (coding exon 8) of the TC2N gene. This alteration results from a T to C substitution at nucleotide position 970, causing the cysteine (C) at amino acid position 324 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
