The c.1743A>C (p.K581N) alteration is located in exon 9 (coding exon 7) of the HDX gene. This alteration results from a A to C substitution at nucleotide position 1743, causing the lysine (K) at amino acid position 581 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
