The c.1051C>A (p.Q351K) alteration is located in exon 6 (coding exon 6) of the MFSD9 gene. This alteration results from a C to A substitution at nucleotide position 1051, causing the glutamine (Q) at amino acid position 351 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
