The c.1456G>A (p.G486S) alteration is located in exon 14 (coding exon 14) of the AARSD1 gene. This alteration results from a G to A substitution at nucleotide position 1456, causing the glycine (G) at amino acid position 486 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
