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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change falls in intron 9 of the ZDHHC9 gene. It does not directly change the encoded amino acid sequence of the ZDHHC9 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs775743190, gnomAD 0.007%), including at least one homozygous and/or hemizygous individual. 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: 537741). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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. -
