Hereditary ataxia with onset in adulthood v7.10 TUBA4A Sarah Leigh Tag Q3_24_promote_green was removed from gene: TUBA4A.
Tag Q3_24_NHS_review was removed from gene: TUBA4A.
Hereditary ataxia with onset in adulthood v7.10 TUBA4A Sarah Leigh edited their review of gene: TUBA4A: Added comment: The rating of this gene has been updated to green and the mode of inheritance updated to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted following NHS Genomic Medicine Service approval.; Changed mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Hereditary ataxia with onset in adulthood v7.9 TUBA4A Sarah Leigh Source NHS GMS was added to TUBA4A.
Source Expert Review Green was added to TUBA4A.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Hereditary ataxia with onset in adulthood v6.5 TUBA4A Sarah Leigh Tag Q3_24_promote_green tag was added to gene: TUBA4A.
Tag Q3_24_NHS_review tag was added to gene: TUBA4A.
Hereditary ataxia with onset in adulthood v6.5 TUBA4A Sarah Leigh changed review comment from: At least seven TUBA4A variants have been associated with Amyotrophic lateral sclerosis 22 with or without frontotemporal dementia, (OMIM:616208)(PMID: 25374358; 37418012; 38884572). Spastic ataxia has been noted as an additional phenotypic feature in patients reported by PMID: 37418012;38884572. Furthermore, cultured fibroblasts from 3 patients with different TUBA4A missense variants, showed significant alterations in microtubule organization and dynamics (PMID: 38884572).; to: At least 15 TUBA4A variants have been associated with Amyotrophic lateral sclerosis 22 with or without frontotemporal dementia, (OMIM:616208)(PMID: 25374358; 37418012; 38884572). Spastic ataxia (in 4/13 unrelated cases) and nystagmus (in 5/13 unrelated cases) have been noted as additional phenotypic features in patients reported by PMID: 37418012; 38884572. Furthermore, functional studies show that missense TUBA4A variants significantly alter the microtubule organization and dynamics, diminishing its repolymerization capability (PMID: 25374358; 38884572).
