The c.1939A>G (p.K647E) alteration is located in exon 18 (coding exon 15) of the DZIP1 gene. This alteration results from a A to G substitution at nucleotide position 1939, causing the lysine (K) at amino acid position 647 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
