The c.1106A>G (p.Q369R) alteration is located in exon 3 (coding exon 1) of the MFSD6 gene. This alteration results from a A to G substitution at nucleotide position 1106, causing the glutamine (Q) at amino acid position 369 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
