The c.2293G>A (p.G765S) alteration is located in exon 21 (coding exon 18) of the DZIP1 gene. This alteration results from a G to A substitution at nucleotide position 2293, causing the glycine (G) at amino acid position 765 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
