The c.1340C>T (p.T447I) alteration is located in exon 10 (coding exon 9) of the SLC41A1 gene. This alteration results from a C to T substitution at nucleotide position 1340, causing the threonine (T) at amino acid position 447 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
