ABSTRACT=<p><bold>Introduction:</bold><italic>PRKCG</italic> mutations have been implicated in the pathogenesis of spinocerebellar ataxia type 14 (SCA14), which is a rare autosomal dominant disease marked by cerebellar degeneration, dysarthria, and nystagmus. Until now, there has never been a report of patients with mutations of c.1232G&gt;C worldwide.</p><p><bold>Case description:</bold> We report a case of a 30-year-old Chinese man with episodic dystaxia, speech disorder, and cognitive impairment; however, his father exclusively exhibited a speech disorder regardless of the same mutation. Whole-exome sequencing revealed a heterozygous c.1232G&gt;C (p.G411A) variant of <italic>PRKCG</italic>.</p><p><bold>Conclusion:</bold> This case presents an extended genotype and phenotype of SCA14, and emphasizes the importance of gene sequencing in patients with spinocerebellar ataxia.</p>
