Ambry Genetics

Dec 06, 2024

The c.86C>G (p.P29R) alteration is located in exon 1 (coding exon 1) of the ADAD2 gene. This alteration results from a C to G substitution at nucleotide position 86, causing the proline (P) at amino acid position 29 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
