The c.874A>G (p.I292V) alteration is located in exon 2 (coding exon 1) of the ABHD13 gene. This alteration results from a A to G substitution at nucleotide position 874, causing the isoleucine (I) at amino acid position 292 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
