The patients were divided into female and male.The data were collected based on province, birthplace province, marital status, and degree of education, parental consanguinity ratio, age, and age of onset of symptoms, age of onset of diagnosis and body mass index (BMI).
Results
Majority of patients (n=169, 59.3%) were male, born in Tehran province (n=81, 28.4%), and live in Tehran province (n=102, 35.8%). Majority of parents (61.1%, n=174) had consanguineous relation and the rest (n=94, 33%) did not have any consanguineous relation. Results show that mean of age, age of diagnosis, mean for expression of first symptoms and mean of time interval between the onset of symptoms and the diagnosis of the disease were 14.52, 2.51, 6.57, and 4.07 years, respectively. Results showed that high percentage of patients (n=191, 67%) had lower BMI (<18.50), and low percentage (n=3, 1.1%) showed higher BMI (>25).
