This study explores various genetic mutations linked to hereditary motor and sensory neuropathy (HMSN) types V and VI. Notable variants, including V273G, R274Q, and others, contribute to the understanding of the genetic basis of these conditions. Previous research by Zhu et al. (2005) and Züchner et al. (2006) highlighted the significance of these mutations in patients presenting with pyramidal signs and optic atrophy. This analysis aims to clarify genotype-phenotype correlations and aid in future diagnostics and treatment strategies.
