The c.2647G>A (p.E883K) alteration is located in exon 21 (coding exon 20) of the NCAPD2 gene. This alteration results from a G to A substitution at nucleotide position 2647, causing the glutamic acid (E) at amino acid position 883 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
