Feb 27, 2024

The c.599C>G (p.S200W) alteration is located in exon 5 (coding exon 5) of the ZDHHC12 gene. This alteration results from a C to G substitution at nucleotide position 599, causing the serine (S) at amino acid position 200 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
