The c.1465C>G (p.L489V) alteration is located in exon 11 (coding exon 10) of the SLC41A1 gene. This alteration results from a C to G substitution at nucleotide position 1465, causing the leucine (L) at amino acid position 489 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This variant has not been reported in the literature in individuals affected with SLC41A1-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant is present in population databases (rs768929818, gnomAD 0.03%). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 489 of the SLC41A1 protein (p.Leu489Val). -
