Backgrounds: Sitosterolemia is an inborn error of sterol metabolism caused by pathogenic variation of ABCG5 or ABCG8. It is characterized by increased plant sterol levels, xanthomas, and accelerated atherosclerosis; however, it is likely to be underdiagnosed in the clinical field. This study aims to describe the genetic variance of clinically confirmed patients with sitosterolemia and analyze the clinical spectrum according to genetic variance.<p class="ab...

Congenital hypothyroidism can be caused by the wrong formation of the thyroid gland or the defect in the synthesis of thyroid hormone. Among the candidate genes, defect in the gene NKX2-1 can be presented as thyroid, lung, or brain dysfunction. An eight-year-old boy was diagnosed as congenital hypothyroidism at the age of 16 days. He was referred to our Pediatric Endocrinology Clinic due to elevated TSH level (36.28uIU/mL). Serum total T3 and free T4 were 125 ng/dL an...

The proband is a 12 yr old Caucasian European girl with grade 3 obesity, developmental delay and hyperphagia. She was born at term via an uncomplicated pregnancy and exhibited neonatal hypotonia, difficulty feeding, failure to thrive and delayed attenuation of milestones. At the age of 2 years she started developing hyperphagia and rapid excessive weight gain. Molecular analysis for Prader Willi syndrome and array CGH were negative. At the age of 10 yrs she was diagnosed with ...

Purpose: Patients with mixed gonadal dysgenesis (MGD) and ovotesticular disorders of sex development (DSD) usually present with asymmetric gonads. Differential diagnosis of these conditions is based on karyotype and pathological findings of gonads. However, it is difficult to determine sex of rearing and to predict long-term outcomes. This study investigated the clinical features, karyotype, sex of rearing, and pubertal outcomes of patients with MGD and ovotesticular DSD.<...

Introduction-Purpose: In addition to chromosomal abnormalities, a number of genes have been implicated as causes of Disorders of Sexual Development (DSD). The NR5A1 (SF-1) gene expresses a transcription factor that plays a role in steroidogenesis by controlling multiple stages of adrenal and gonadal development, and its mutations have been reported in cases of DSD.Case presentation: A 152/12-year-old teenager ...
