The c.1209G>C (p.W403C) alteration is located in exon 2 (coding exon 2) of the ABHD15 gene. This alteration results from a G to C substitution at nucleotide position 1209, causing the tryptophan (W) at amino acid position 403 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
