The c.1187G>A (p.R396H) alteration is located in exon 2 (coding exon 2) of the ABHD15 gene. This alteration results from a G to A substitution at nucleotide position 1187, causing the arginine (R) at amino acid position 396 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
