The c.179A>G (p.N60S) alteration is located in exon 5 (coding exon 3) of the SLC25A40 gene. This alteration results from a A to G substitution at nucleotide position 179, causing the asparagine (N) at amino acid position 60 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
