The c.4685T>C (p.M1562T) alteration is located in exon 8 (coding exon 8) of the NACAD gene. This alteration results from a T to C substitution at nucleotide position 4685, causing the methionine (M) at amino acid position 1562 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
