The c.1324C>G (p.P442A) 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 1324, causing the proline (P) at amino acid position 442 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
