The c.967G>A (p.G323S) alteration is located in exon 7 (coding exon 7) of the ZDHHC18 gene. This alteration results from a G to A substitution at nucleotide position 967, causing the glycine (G) at amino acid position 323 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
