Variant 8-17156815-G-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_016353.5(ZDHHC2):c.92G>C(p.Gly31Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000659 in 151,632 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G31V) has been classified as Uncertain significance.

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]

Ambry Genetics

Jan 04, 2024

The c.92G>C (p.G31A) alteration is located in exon 1 (coding exon 1) of the ZDHHC2 gene. This alteration results from a G to C substitution at nucleotide position 92, causing the glycine (G) at amino acid position 31 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
