Function

The protein encoded by this gene is one of two large subunits of the AP5 adaptor complex.^[6] Variants in this gene have not been implicated in any disease but damaging variants in AP5Z1, the gene encoding the other large subunit in this complex, are associated with SPG48, a type of hereditary spastic paraplegia.^[7][8] In addition, damaging variants in the genes encoding two proteins that stably associate with the AP-5 adaptor complex are also associated with forms of hereditary spastic paraplegia - SPG11 with the disease of the same name^[9] and ZFYVE26 with SPG15.^[10]

GnomAD reports an observed v. expected ratio of predicted loss-of-function variants of 0.84 (0.58 - 1.24) for AP5B1.^[11][12]
