KIF5A and hereditary spastic paraplegia: For instance, recent reports have highlighted how such genes as DCTN1 (dynactin 1) [76–78], GDAP1 (ganglioside-induced differentiation associated protein 1) [76, 79, 80], DYNC1H1 (Dynein, cytoplasmic 1, heavy chain 1) [81, 82], KIF5A (Kinesin Heavy Chain Isoform 5A) [81, 83], NEFH (neurofilament heavy chain gene) [84, 85] have all been associated with a wide range of phenotypes, ranging from ALS to hereditary spastic paraparesis (HSP) [86], dSMA or even classic Charcot–Marie–Tooth disease [76, 81, 82].
