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]

not provided, no classification provided	phenotyping only	GenomeConnect - Brain Gene Registry	-	Variant interpreted as Uncertain significance and reported on 07-01-2019 by Invitae . Assertions are reported exactly as they appear on the patient provided laboratory report. GenomeConnect does not attempt to reinterpret the variant. The IDDRC-CTSA National Brain Gene Registry (BGR) is a study funded by the U.S. National Center for Advancing Translational Sciences (NCATS) and includes 13 Intellectual and Developmental Disability Research Center (IDDRC) institutions. The study is led by Principal Investigator Philip Payne PhD, FACMI from Washington University. The BGR is a data commons of gene variants paired with subject clinical information. This database helps scientists learn more about genetic changes and their impact on the brain and behavior. Participation in the Brain Gene Registry requires participation in GenomeConnect. More information about the Brain Gene Registry can be found on the study website - https://braingeneregistry.wustl.edu/. -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Sep 30, 2023	This variant has not been reported in the literature in individuals affected with ZDHHC9-related conditions. ClinVar contains an entry for this variant (Variation ID: 569982). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. This variant is present in population databases (rs753807510, gnomAD 0.002%), including at least one homozygous and/or hemizygous individual. This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 338 of the ZDHHC9 protein (p.Pro338Leu). -
