Jul 19, 2022

The c.1159G>A (p.E387K) alteration is located in exon 9 (coding exon 9) of the MFSD7 gene. This alteration results from a G to A substitution at nucleotide position 1159, causing the glutamic acid (E) at amino acid position 387 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
