The c.746G>A (p.R249H) alteration is located in exon 4 (coding exon 3) of the ABHD17B gene. This alteration results from a G to A substitution at nucleotide position 746, causing the arginine (R) at amino acid position 249 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
