The c.694A>G (p.K232E) alteration is located in exon 4 (coding exon 2) of the HDX gene. This alteration results from a A to G substitution at nucleotide position 694, causing the lysine (K) at amino acid position 232 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
