Ambry Genetics

Jan 10, 2023

The c.680G>A (p.R227Q) alteration is located in exon 5 (coding exon 5) of the ABHD14A gene. This alteration results from a G to A substitution at nucleotide position 680, causing the arginine (R) at amino acid position 227 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
