The c.241A>G (p.I81V) alteration is located in exon 2 (coding exon 2) of the SLC27A1 gene. This alteration results from a A to G substitution at nucleotide position 241, causing the isoleucine (I) at amino acid position 81 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
