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]

Syndromic X-linked intellectual disability Raymond type Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeOct 16, 2023This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 310 of the ZDHHC9 protein (p.Arg310Gln). This variant is present in population databases (rs753387074, gnomAD 0.008%). 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: 575731). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ZDHHC9 protein function. 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. -
