The c.226A>C (p.M76L) alteration is located in exon 3 (coding exon 2) of the ABHD6 gene. This alteration results from a A to C substitution at nucleotide position 226, causing the methionine (M) at amino acid position 76 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
