However, there are indications that neurodevelopment remains affected: pediatric ALS patients carrying fus NLS mutations may present initially with learning disabilities, tremor, and mild motor developmental delay (Picher-Martel et al., 2020), and heterozygous FUS(ΔNLS) mice likely display developmental dendritic excitability changes (Sahadevan et al., 2021). The gene discussed is FUS; the disease is amyotrophic lateral sclerosis.
