The c.1172G>A (p.R391H) alteration is located in exon 9 (coding exon 8) of the SLC41A1 gene. This alteration results from a G to A substitution at nucleotide position 1172, causing the arginine (R) at amino acid position 391 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 391 of the SLC41A1 protein (p.Arg391His). This variant is present in population databases (rs368438972, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SLC41A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2395902). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
