Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is an autosomal recessive disease in which adrenal synthesis of glucocorticoids and mineralocorticoids is impaired and steroid biosynthesis is directed toward the formation of excessive androgens. Persistently high androgens will accelerate bone maturation and reduce final adult height.Objectives: To assess the efficacy of androgen antagonist Flutamide and aromatase inhibitor Tastolact...

Ovotesticular disorder of sex development (OT-DSD) is a rare disorder of sexual differentiation characterized by the presence of both testicular and ovarian tissues in the gonads of the same individual. Patients usually present at birth with ambiguous genitalia, and the majority showed a 46,XX karyotype, with absence of the SRY sequence. In this study we reported on nine patients with OT-DSD, who were referred to the Human Genetics and endocrinology Clinics, division ...

Background: Mutations in CYP19A1 gene have been described in both females and males and to date only 20 cases with aromatase deficiency have been reported. In newborns, aromatase deficiency should be considered in the aetiology of 46, XX DSD, after ruling out congenital adrenal hyperplasia.Objective and hypotheses: Report of a case with CYP19A1 mutation.Method: Here we report a patient who was presenting at the age of 20 years old ...

Background: Virilization at puberty in girls remains a challenge. Several differential diagnoses must be considered including disorders of sex development (DSD) and tumors.Case Report: We report an 11.5-year-old girl who was referred to our center for progressive cliteromegaly since 6 months. Past medical history was remarkable for prematurity of 36 weeks gestation and for mild ongoing psychomotor delay. At presentation ...

Disorders of sex development (DSD) have defined as congenital conditions in which the development of chromosomal, gonadal, or anatomical sex is atypical. Wilms tumor 1(WT1) gene mutations have been described in 46,XY patients with ambiguous genitalia or complete gonadal dysgenesis with or without Wilms tumor, nephropathy, gonadoblastoma and other defects e.g. cryptorchidism, hypospadias. Sex chromosome mosaicism is a major cause of DSD with a wide phenotypic variability. The p...

Patients usually present at birth with ambiguous genitalia, and the majority showed a 46,XX karyotype, with absence of the SRY sequence.

Background: Sex chromosome DSD constitute an important category in the definition of DSD.Objective and hypotheses: The study included 379 patients comprising a wide spectrum of presenting features, associated with different arrays of chromosomal abnormalities aiming at. Studying the prevalence of Sex chromosomal abnormalities among DSD patients.Method: Patients were subjected to detailed clinical examination, pubertal staging, cyto...

Background: Persistent Müllerian duct syndrome (PMDS) is a relatively rare autosomal recessive disorder of sex development (DSD), characterized by the presence of Müllerian duct derivatives in 46,XY phenotypic males. PMDS is due to mutations in the AMH gene or its type II receptor gene AMHR2. To date; more than 50 different mutations of the anti-Müllerian hormone (AMH) gene have been reported.Case report: Here, we report a novel mutation o...

Disorders of sex development (DSDs)represent a diverse group of clinical conditions which have a very wide phenotypic spectrum associated with a complicated molecular background.Such conditions are considered among the most common birth defects andare frequently associated with congenital abnormalities.Herein we present 62 patients with DSD associated with somatic anomalies. Patients were selected from clinical genetics dept., NRC. They underwent complet...

Background: 46,XX DSD (Disorder of Sex Development) includes individuals with ovotestes (ovotesticular DSD (OTDSD)) or testes (testicular DSD (TDSD)). Most individuals with 46,XX TDSD carry the SRY gene. Other known causes of TDSD/OTDSD include chromosomal rearrangements involving SOX9 or SOX3 and mutations of WNT4 and a WNT regulator, R-SPONDIN 1. However, our understanding of the molecular causes of TDSD and OTDSD remain incomplete.<p ...
