The c.1204G>A (p.E402K) alteration is located in exon 10 (coding exon 10) of the EXD1 gene. This alteration results from a G to A substitution at nucleotide position 1204, causing the glutamic acid (E) at amino acid position 402 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
