Collection Method: clinical testing

The c.1535G>C (p.G512A) alteration is located in exon 1 (coding exon 1) of the MFSD6L gene. This alteration results from a G to C substitution at nucleotide position 1535, causing the glycine (G) at amino acid position 512 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
