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]

ClinVar contains an entry for this variant (Variation ID: 412228). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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. This variant has not been reported in the literature in individuals affected with AP5Z1-related conditions. This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 488 of the AP5Z1 protein (p.Pro488Leu). This variant is present in population databases (rs372654170, gnomAD 0.04%). -
