The c.52C>G (p.Q18E) alteration is located in exon 3 (coding exon 2) of the DZIP3 gene. This alteration results from a C to G substitution at nucleotide position 52, causing the glutamine (Q) at amino acid position 18 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
