CIC mutations are also related to clinical symptoms, the probability of samples without headache having CIC mutations is significantly greater than the probability of samples with headache ( p = 0.0119), and there is a possible trend that the probability of CIC mutation in samples without visual change is greater than samples with visual changes ( p = 0.0646), there is also a strong tendency that the probability of CIC mutation in samples without sensory change is greater than samples with sensory change ( p = 0.0563) ( Table 1 ).
