Hereditary ataxia with onset in adulthood v8.24 NEU1 Arina Puzriakova Source Expert Review Green was added to NEU1.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Hereditary ataxia with onset in adulthood v8.3 NEU1 Arina Puzriakova Classified gene: NEU1 as Amber List (moderate evidence)
Hereditary ataxia with onset in adulthood v8.3 NEU1 Arina Puzriakova Added comment: Comment on list classification: Biallelic variants in the NEU1 gene are associated with Sialidosis (OMIM: 256550). Both Sialidosis Type I (milder, late-onset) and Sialidosis Type II (more severe, early-onset) can present with ataxia as part of a systemic neurological condition.

Overall there are sufficient unrelated cases to warrant inclusion on this panel.
Hereditary ataxia with onset in adulthood v8.3 NEU1 Arina Puzriakova Gene: neu1 has been classified as Amber List (Moderate Evidence).
Hereditary ataxia with onset in adulthood v8.2 NEU1 Arina Puzriakova Tag Q2_25_ promote_green tag was added to gene: NEU1.
Tag Q2_25_ NHS_review tag was added to gene: NEU1.
Hereditary ataxia with onset in adulthood v8.2 NEU1 Arina Puzriakova Phenotypes for gene: NEU1 were changed from Ataxia; myoclonus to Sialidosis, type I, OMIM:256550; Sialidosis, type II, OMIM:256550; Ataxia; Myoclonus
Hereditary ataxia with onset in adulthood v7.15 NEU1 Lauren Turton gene: NEU1 was added
gene: NEU1 was added to Hereditary ataxia with onset in adulthood. Sources: NHS GMS

Publications for gene: NEU1 were set to 10944856; 11063730; 32752208; 31371146; 30023283
Phenotypes for gene: NEU1 were set to Ataxia; myoclonus
Review for gene: NEU1 was set to GREEN
gene: NEU1 was marked as current diagnostic
Added comment: NEU1-related sialidosis type I is a milder form of the disorder, characterised by visual defects, macular cherry-red spot, myoclonus, ataxia, and seizures. Onset can be variable from childhood to adulthood. Disorder has been well characterised for many years, with several unrelated patients reported.
