Genes affected

ZDHHC2 (HGNC:18469): (zinc finger DHHC-type palmitoyltransferase 2) Enables protein homodimerization activity and protein-cysteine S-palmitoyltransferase activity. Involved in several processes, including peptidyl-L-cysteine S-palmitoylation; regulation of protein catabolic process; and regulation of protein localization to plasma membrane. Located in Golgi apparatus and endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.485A>G (p.N162S) alteration is located in exon 7 (coding exon 7) of the ZDHHC2 gene. This alteration results from a A to G substitution at nucleotide position 485, causing the asparagine (N) at amino acid position 162 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
