From NCBI Gene:
This gene encodes a member of the phospholipase D (PLD) family of enzymes that catalyze the hydrolysis of membrane phospholipids. The encoded protein is a single-pass type II membrane protein and contains two PLD phosphodiesterase domains. This protein influences processing of amyloid-beta precursor protein. Mutations in this gene are associated with Alzheimer disease risk. Alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Apr 2014]
5'->3' DNA exonuclease which digests single-stranded DNA (ssDNA) (PubMed:30312375). Regulates inflammatory cytokine responses via the degradation of nucleic acids, by reducing the concentration of ssDNA able to stimulate TLR9, a nucleotide-sensing receptor in collaboration with PLD4 (By similarity). May be important in myotube formation (PubMed:22428023). Plays a role in lysosomal homeostasis (PubMed:28128235). Involved in the regulation of endosomal protein sorting (PubMed:29368044).

- SPINOCEREBELLAR ATAXIA 46
Spinocerebellar ataxia 46 (SCA46): A form of spinocerebellar ataxia, a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA46 is a slowly progressive, autosomal dominant form with onset in adulthood. [MIM:617770]
Genetic variants in PLD3 have been suggested to be associated with an increased risk for Alzheimer disease (PubMed:24336208, PubMed:25832409). Further studies, however, did not support PLD3 involvement in this disease (PubMed:25832408, PubMed:25832411, PubMed:25832413, PubMed:25832410, PubMed:26411346). Futhermore, it is controversial whether PLD3 plays a role in amyloid precursor protein processing (APP) or not (PubMed:24336208). In a relevant Alzheimer's disease mouse model PLD3 deficiency does not affect APP metabolism or amyloid plaque burden (PubMed:28128235). However one study shown that PLD3 influences APP processing (PubMed:24336208).
