The c.1298C>T (p.S433F) alteration is located in exon 8 (coding exon 8) of the SLC41A2 gene. This alteration results from a C to T substitution at nucleotide position 1298, causing the serine (S) at amino acid position 433 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
