The c.847G>A (p.V283M) alteration is located in exon 9 (coding exon 8) of the ABHD6 gene. This alteration results from a G to A substitution at nucleotide position 847, causing the valine (V) at amino acid position 283 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
