Ambry Genetics

Jan 26, 2023

The c.281G>A (p.R94H) alteration is located in exon 3 (coding exon 3) of the ABHD4 gene. This alteration results from a G to A substitution at nucleotide position 281, causing the arginine (R) at amino acid position 94 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
