Ambry Genetics

Nov 08, 2022

The c.1384G>C (p.A462P) alteration is located in exon 10 (coding exon 9) of the ANKRD55 gene. This alteration results from a G to C substitution at nucleotide position 1384, causing the alanine (A) at amino acid position 462 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
