Feb 23, 2023

The c.487A>G (p.I163V) 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 487, causing the isoleucine (I) at amino acid position 163 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
