Genes affected
ZDHHC15 (HGNC:20342): (zinc finger DHHC-type palmitoyltransferase 15) The protein encoded by this gene belongs to the DHHC palmitoyltransferase family. Mutations in this gene are associated with mental retardatio X-linked type 91 (MRX91). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
