Genes affected

ZDHHC9 (HGNC:18475): (zinc finger DHHC-type palmitoyltransferase 9) This gene encodes an integral membrane protein that is a member of the zinc finger DHHC domain-containing protein family. The encoded protein forms a complex with golgin subfamily A member 7 and functions as a palmitoyltransferase. This protein specifically palmitoylates HRAS and NRAS. Mutations in this gene are associated with X-linked cognitive disability. Alternate splicing results in multiple transcript variants that encode the same protein.[provided by RefSeq, May 2010]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jun 12, 2018	In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with ZDHHC9-related disease. This variant is present in population databases (rs748573163, ExAC 0.01%). This sequence change replaces serine with leucine at codon 334 of the ZDHHC9 protein (p.Ser334Leu). The serine residue is moderately conserved and there is a large physicochemical difference between serine and leucine. -
