Amyotrophic lateral sclerosis -plus patient with an intermediate-length CACNA1A allele: a Case Report.
- Open access
An elderly woman with bulbar-onset ALS and cerebellar symptoms carried an intermediate-length CACNA1A allele, marking the first such case reported in the Chinese population.
- Why it matters: Understanding genetic factors in ALS and its phenotypic spectrum is crucial for diagnosis and potential targeted therapies, especially when atypical features like cerebellar involvement are present.
- What they did: The case involved genetic analysis revealing a CAG repeat genotype of 10/20 in CACNA1A, alongside clinical features including cognitive impairment and cerebellar signs, with her son showing isolated cerebellar ataxia.
- The result: This case suggests a possible, but unconfirmed, link between intermediate-length CACNA1A alleles and ALS, highlighting the need for further research into genetic contributions to phenotypic variability in motor neuron diseases.
