Ataxia v2.65 GLS Bryony Thompson Marked gene: GLS as ready
Ataxia v2.65 GLS Bryony Thompson Gene: gls has been classified as Green List (High Evidence).
Ataxia v2.65 GLS Bryony Thompson Classified gene: GLS as Green List (high evidence)
Ataxia v2.65 GLS Bryony Thompson Gene: gls has been classified as Green List (High Evidence).
Ataxia v2.64 GLS Bryony Thompson gene: GLS was added
gene: GLS was added to Ataxia. Sources: Literature
Mode of inheritance for gene: GLS was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: GLS were set to 38877099; 38260514; 35913761; 30970188
Phenotypes for gene: GLS were set to glutaminase deficiency, MONDO:0600001
Review for gene: GLS was set to GREEN
Added comment: PMID 30970188 reports three families and PMID 35913761 reports two families (total five families, six patients) with biallelic GLS loss‑of‑function variants (5'UTR repeat expansions, frameshift, nonsense or missense coding changes) causing early‑onset developmental delay, progressive cerebellar ataxia and markedly elevated plasma glutamine. Functional studies show ~4‑fold reduced GLS mRNA in patient iPSCs, markedly decreased enzyme activity in patient fibroblasts, and zebrafish glsa knockdown recapitulating neurodevelopmental defects, though rescue experiments are lacking. These findings align with the Ataxia panel because progressive ataxia is a core feature of the panel’s scope of neurological disorders with ataxia.
