Ambry Genetics

Dec 21, 2022

The c.323G>C (p.R108P) alteration is located in exon 3 (coding exon 2) of the ANKRD65 gene. This alteration results from a G to C substitution at nucleotide position 323, causing the arginine (R) at amino acid position 108 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
