The c.191G>A (p.S64N) alteration is located in exon 2 (coding exon 2) of the ABHD3 gene. This alteration results from a G to A substitution at nucleotide position 191, causing the serine (S) at amino acid position 64 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
