Genes affected
AP5Z1 (HGNC:22197): (adaptor related protein complex 5 subunit zeta 1) This gene was identified by genome-wide screen for genes involved in homologous recombination DNA double-strand break repair (HR-DSBR). The encoded protein was found in a complex with other proteins that have a role in HR-DSBR. Knockdown of this gene reduced homologous recombination, and mutations in this gene were found in patients with spastic paraplegia. It was concluded that this gene likely encodes a helicase (PMID:20613862). [provided by RefSeq, Jan 2011]

Hereditary spastic paraplegia 48 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 05, 2018 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in AP5Z1 are known to be pathogenic (PMID: 20613862, 27606357). This variant has not been reported in the literature in individuals with AP5Z1-related conditions. ClinVar contains an entry for this variant (Variation ID: 578441). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Gln236*) in the AP5Z1 gene. It is expected to result in an absent or disrupted protein product. - |
