Answer:
Neuron would be unable to receive signal from environment and previous neuron.
Explanation:
A neuron cell comprises of dendrites, cell body and axon. Dendrites are the projections of neuron cells that receive the electrochemical signal from other neurons and transfer them to soma (body) of a neuron cell. While axon transfer it to next neuron from cell body.
So if the mutation cause loss of dendrites of neuron cells it would be unable to receive the signal from the previous neuron and environment because receptors to receive signals are present on dendrites. Consequently the cell would loss the communication with other cell and that cell may dies and it can also cause paralysis of that particular area because of loss of communication.
