Aminoacidopathy v1.66 SLC1A3 Sangavi Sivagnanasundram gene: SLC1A3 was added
gene: SLC1A3 was added to Aminoacidopathy. Sources: ClinGen
Mode of inheritance for gene: SLC1A3 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: SLC1A3 were set to 27829685, 16116111, 29062094, 19139306, 29208948, 29066757, 32754645, 25497598
Phenotypes for gene: SLC1A3 were set to episodic ataxia type 6 MONDO:0012982
Mode of pathogenicity for gene: SLC1A3 was set to Other
Review for gene: SLC1A3 was set to GREEN
Added comment: Variants reported in 8 unrelated probands with reported errors in glutamate metabolism. Mechanism of disease varies depending on the mutation. The most severe variants (p.M128R, p.P290R, and p.T318A) appear to have gain of function mechanism.

Aminoacidopathy v1.66 OTC Sangavi Sivagnanasundram gene: OTC was added
gene: OTC was added to Aminoacidopathy. Sources: Other
Mode of inheritance for gene: OTC was set to X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
Publications for gene: OTC were set to 26059767
Phenotypes for gene: OTC were set to ornithine carbamoyltransferase deficiency MONDO:0010703
Review for gene: OTC was set to GREEN
Added comment: Well established gene-disease association where affected individuals have a deficiency in carbamoyltransferase which affects the urea cycle.

Mode of inheritance for gene: ALDH18A1 was set to BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Publications for gene: ALDH18A1 were set to 32017139, 26026163, 26320891
Phenotypes for gene: ALDH18A1 were set to P5CS deficiency MONDO:0100126
Added comment: Classified Definitive on 18/05/2021 by ClinGen Aminoacidopathy GCEP - https://search.clinicalgenome.org/CCID:004093

P5CS is an important enzyme in several amino acid pathways. >10 Individuals with abnormal biochemistry and function studies have been conducted.

Mechanism of disease is variable LOF depending on the mutation present which results in the spectrum of severity in the phenotype.
Dominant negative mutations have a less severe phenotype (AD cutis laxa/hsp) to the severely affected proteins having no activity (AR cutis laxa/hsp) (PMID: 32017139).
