ARID1B and sleep apnea syndrome: ARID1B-ID patients appeared to have a higher prevalence of myopia (p = 0.020), cryptorchidism (p = 0.023), constipation (p = 0.002), sleep apnea (p = 0.026), hyperactivity (p = 0.026), and high pain threshold (p = 0.044), although these differences are not statistically significant under the Bonferroni adjusted significance level.
