轴突

Axonal degeneration similar to that observed in KIF 1A mutants has also been reported for several neurodegenerative diseases such as senile dementia and most recently Charcot-Marie-Tooth disease type 2A by another synaptic vesicle precursors transporter KIF1B knockout mice. In some neurodegenerative diseases, neuronal cell death caused by defects in the transport of synaptic vesicle precursors by KIF1A may be involved.

和KIF1A基因剔除鼠相似的轴突变性在一些神经退行性疾病如老年性痴呆的研究中也有发现，特别是最近，与KIF1A一样运输突触小泡前体的KIF1B基因剔除鼠与Charcot-Marie-Tooth二型疾病的关系，更提示了KIF1A基因的功能缺失，与神经退行性病变及神经元死亡的发生有不可分割的关系。
