The c.2384G>A (p.G795D) alteration is located in exon 12 (coding exon 12) of the ZCCHC14 gene. This alteration results from a G to A substitution at nucleotide position 2384, causing the glycine (G) at amino acid position 795 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
