Ambry Genetics

Feb 14, 2023

The c.64C>T (p.P22S) alteration is located in exon 1 (coding exon 1) of the ARRDC2 gene. This alteration results from a C to T substitution at nucleotide position 64, causing the proline (P) at amino acid position 22 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
