The c.1289C>G (p.S430W) alteration is located in exon 6 (coding exon 6) of the MFSD9 gene. This alteration results from a C to G substitution at nucleotide position 1289, causing the serine (S) at amino acid position 430 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
