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]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant X-129829133-TAGCG-T is Pathogenic according to our data. Variant chrX-129829133-TAGCG-T is described in ClinVar as [Pathogenic]. Clinvar id is 10709.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chrX-129829133-TAGCG-T is described in Lovd as [Pathogenic].
