The c.1123G>A (p.A375T) alteration is located in exon 8 (coding exon 8) of the MFSD7 gene. This alteration results from a G to A substitution at nucleotide position 1123, causing the alanine (A) at amino acid position 375 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
