The c.4168G>A (p.V1390M) alteration is located in exon 3 (coding exon 3) of the NACAD gene. This alteration results from a G to A substitution at nucleotide position 4168, causing the valine (V) at amino acid position 1390 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
