SACS and Motor axonal neuropathy: Besides the three that will be discussed below, DNAJC19 (TIM14) and DNAJC29 (sacsin) are linked to forms of ataxia, DNAJB2 (HSJ1) is linked with distal motor neuropathy, DNAJC12 is associated with phenylketonuria-related neurodevelopmental deficits, and DNAJB6 (Mrj) is linked with limb-girdle muscular dystrophy type 1D (Koutras and Braun, 2014; Anikster et al., 2017).
