Gene: KIAA0319L

Green List (high evidence)

Evidence Summary from Illumina curation team: KIAA0319L, also known as AAVR or AAVRL, encodes the KIAA0319 like protein, a type-I transmembrane protein which acts as an essential receptor for adeno-associated virus (AAV) and is involved in adeno-associated virus infection through endocytosis system (PMID 26814968: Pillay et al. 2016). Genetic ablation of AAVR renders a wide range of mammalian cell types highly resistant to AAV infection. Adeno-associated virus vectors are widely used in virus-based gene therapy because of their broad tissue tropism, non-pathogenic nature and low immunogenicity. PMID 26814968: Pillay et al. (2016) - used a haploid genetic screen to identify the type I transmembrane protein KIAA0319L as an essential receptor that mediates AAV entry and renamed this protein the AAV receptor (AAVR). The function of AAVR was confirmed by using CRISPRCas9 to knock out the receptor and by using anti-AAVR blocking antibodies; both treatments rendered cells highly resistant to AAV infection with several serotypes, including AAV2, which is the most commonly used serotype for gene therapy in clinical trials. Finally, Aavr knockout mice were more resistant to AAV-mediated gene therapy than mice that expressed AAVR. PMID 28679762: Pillay et al. (2017) - Further defines AAV-AAVR interactions, genetically and biochemically.
