Variant Ataxia Telangiectasia: A Novel ATM Gene Mutation With Disabling Tremor and Response to Deep Brain Stimulation
Objective: We describe a patient with a novel ATM gene variant presenting with tremor, neuropathy, and late-onset ataxia. Background: Ataxia Telangiectasia (AT) is an autosomal…Progressive Cerebellar Ataxia as the Predominant Symptomatology of SGP-7 Compound Heterozygote Pathogenic Variants related HSP-7
Objective: Analyze a clinical case detailing the presentation of a patient primarily exhibiting gradual onset balance disturbances, subsequently diagnosed with HSP-7, elucidating key diagnostic challenges…Utility of Whole Exome Sequencing in movement disorders potentially related to Mitochondrial cytopathies
Objective: To describe the clinic-genetic profile of clinically suspected mitochondrial cytopathies with movement disorders (MDs). Background: Literature on the clinico-genetic spectrum of movement disorders related…Novel Partial Gene Deletion in CaCNA1A Presenting with Gait Ataxia, Vertigo, and Abnormal Eye Movements
Objective: To report a partial gene deletion in CaCNA1A associated with ataxia. Background: CaCNA1A gene, located on chromosome 19p, encodes the alpha-1a subunit of the…Spinocerebellar Ataxia Type 49 presenting with Early onset Dystonia-Ataxia in an Indian Female
Objective: To report the first Indian patient with SCA 49 who presented in the second decade and to expand the clinical phenotype to include dystonic…Complex Movement Disorders in Late Onset TPP1 Gene Mutation (Atypical Neuronal Ceroid Lipofuscinosis Type 2)
Objective: To describe an atypical late onset phenotypical presentation of a homozygous TPP1 mutation with complex movement disorders. Background: TPP1 mutations, lead to deficiency of…The first Indian patient with Hereditary Spastic Paraparesis type 42 due to a de novo SLC33A1 variant
Objective: Hereditary Spastic Paraparesis (HSP) 42 is an autosomal dominant HSP caused by pathogenic mutations in the SLC33A1 gene. This subtype has been reported from a…An Unusual and Treatable Cause of Cerebellar Ataxia and Dystonia: Homozygous COQ4 Gene Mutation
Objective: To report a case of Coenzyme Q10 (CoQ10) deficiency due to COQ4 variants causing adult-onset ataxia and dystonic postures. Background: CoQ10 is an essential…A Novel SLC9A1 Mutation Associated with Cerebellar Ataxia and Sensorineural Hearing Loss
Objective: To report a novel genetic mutation in the SLC9A1 gene presenting with childhood onset ataxia and sensorineural hearing loss. Background: Lichtenstein-Knorr syndrome is a…Mixed Cerebellar Ataxia in a Patient with a Novel FAT2 Gene Variant Associated with SCA45
Objective: We describe a patient with late-onset ataxia, cognitive impairment, and parkinsonism with a novel missense variant in FAT2, a gene implicated in spinocerebellar ataxia…
