Eleanor Williams changed review comment from: Argininosuccinic aciduria (ASA) is caused by homozygous mutation in the gene encoding argininosuccinate lyase (ASL). Onset is typically in the neonatal period or in late infancy. The association of biallelic variants in ASL and the phenotype of Argininosuccinic aciduria is well established. e.g. PMID: 12384776 - Linnebank et al 2002 - homozygous/compound het variants in ASL in 27 unrelated individuals of different ancestries. No phenotype information is given. They also found a complete homologue of this gene on chr 22 which is predicted to encode an immunoglobulin-lambda-like mRNA. PMID: 17326097 - Trevisson et al 2007 - report homozygous/compound het variants in ASL in 12 Italian patients with ASA. Ataxia is not mentioned as a phenotypic feature. PMID: 29326055 - AlTassan et al 2018 - a retrospective review of 54 Saudi Arabian patients with ASA from January 2000 to December 2015. 35 patients (63%) had genetic data available all with variants in the ASL gene; c.1060C > T; p.(Gln354*) in 26 patients (likely founder mutation); c.556C > T; p.(Arg186Trp) in 7 patients, c.602+1G > T in one patient and 1062+5G > C in one patient. 7/10 patients are reported to show spasticity although it is not reporterd whether they all shared the same founder variant in ASL. More recent retrospectives show that ataxia is reported in approx. 10% of individuals with Argininosuccinic aciduria. 2 cases with ataxia and ASL variant identified are reported. PMID: 38044746 - Gurung et al 2023 - conducted a UK national multicentre retrospective study assessing the movement disorder phenotype in ASA patients from July 2015 to June 2022. 60 patients were studied with a median age of 12.7 years (range: 6 months to 53 years). 17 (28%) individuals had ASA with neurodegenerative-related symptoms, movement disorder, hypotonia/fatigue and abnormal behaviour. Of these 4 were reported to show tremor/dystonia, with this phenotype present at ages 9, 11, 24 and 25 years of age. Homozygous or compound het ASL variants were recorded in 25/60 patients including 3 out of the 4 patients with tremor/dystonia (patients 4,9 and 25 with c.719-2A>G; c.857A>G, c.1153C>T; c.1153C>T and c.437G>A; c.446+1G>A respectively). Genotype data was not available for other patients. Although patient 4 from this study and patient 9 from the Baruteau et al 2017 study share the same genotype and are both male, their phenotypic descriptions differ so assuming here that they are not the same patient. PMID: 28251416 - Baruteau et al 2017 - conducted a retrospective and prospective analysis of patients in the UK with ASA from March 2013 - December 2015. Tremors or dystonia were reported in 4 individuals (1,4,9 and 25). All were diagnosed before the age of 3 although it is not stated at what age the tremors/dystonia were first noted. The first 3 of these patients had homozygous or compound het variants in ASL identified (c.35G>A;c.35G>A, c.377G>A;c.377G>A and c.719-2A>G, c.857A>G respectively).

More recent retrospectives show that tremors and/or dystonia is reported in some individuals with Argininosuccinic aciduria. 6 cases with ataxia and ASL variant identified are reported.
