  • Spinocerebellar Ataxias (SCA) Comprehensive Panel

    Spinocerebellar ataxias (SCA) are a group of hereditary neurological disorders characterized by slowly progressive ataxia accompanied by cerebellar degeneration. Ataxia is gait imbalance associated with limb incoordination and loss of fine and gross motor control. The most common types of SCA are…

  • Heart and Nervous System Pathology in Compound Heterozygous Friedreich Ataxia

    In a small percentage of patients with Friedreich ataxia (FA), the pathogenic mutation is compound heterozygous, consisting of a guanine–adenine–adenine (GAA) trinucleotide repeat expansion in one allele, and a deletion, point mutation, or insertion in the other. In 2 cases of compound heterozygous…

  • Cerebellar Ataxia

    Cerebellar ataxias are a highly heterogeneous group of genetic disorders distinguished by abnormal wide-based gait, irregular eye and hand movements, speech difficulties, and morphologically characterized by cerebellar atrophy. Ataxia is a neurological feature of abnormal gait due to the lack of…

  • Niemann–Pick Type C in Early-Onset Ataxia

    Niemann-Pick disease type C (NP-C) is a rare multisystemic lysosomal disorder which, albeit treatable, is still starkly underdiagnosed. As NP-C features early onset ataxia (EOA) in 85-90 % of cases, EOA presents a promising target group for undiagnosed NP-C patients.
