Ambry Genetics

Apr 12, 2022

The c.68C>G (p.P23R) alteration is located in exon 1 (coding exon 1) of the ABHD14A gene. This alteration results from a C to G substitution at nucleotide position 68, causing the proline (P) at amino acid position 23 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
