Institutionalized adults with mental retardation (N = 297) were surveyed to determine the prevalence of symptoms of Rett syndrome. No symptom of the syndrome occurred more frequently in males than females. When symptoms were analyzed in clusters (e.g., severe mental retardation, no prenatal complications, walked before 15 months, and wide-based gait), no single cluster of symptoms appeared to differentiate males from females. However, as individuals, only females were found to meet the necessary criteria for a diagnosis of Rett syndrome. Symptoms were seen with equal frequency in this population and no one or two symptoms differentiated patients with and without Rett syndrome.
对297名患有智力障碍的机构收容成年人进行了调查，以确定雷特综合征症状的患病率。该综合征的症状在男性中出现的频率并不高于女性。当对症状进行分组分析时（例如，严重智力障碍、无产前并发症、15个月前会走路和宽基步态），没有一组症状似乎能区分男性和女性。然而，就个体而言，只有女性被发现符合雷特综合征诊断的必要标准。在这一人群中，症状出现的频率相同，没有一两种症状能区分患有和未患有雷特综合征的患者。
