Hypospadias in a Male Patient with 21-Hydroxylase Deficiency and Atypical Clinical Course: Presentation of Two Brothers

Guven Ayla , Hancili Suna , Arlt Wiebke

Introduction: 21-Hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia (CAH). Clinical and laboratory findings vary depending on the enzyme activity.Case Report 1: A 2-month-old male infant referred as hypospadias. He was born at term from consanguineous parents with intrauterine growth retardation. The mother had no problem during pregnancy. The external genitalia had penoscrotal hypospadias with chordee and both teste...

An Ovulating Testis

Kothandapani Jaya Sujatha Gopal , Sachdev Pooja , Wright Neil

Background: Ovotesticular disorders of sexual development (DSD) are a rare form of DSD with co-existence of both ovarian and testicular tissue in one or both gonads.Case report: A term infant (weight +1.38 SDS) presented at birth with severe penoscrotal hypospadias, a small phallus and a right hemiscrotum with descended gonad (external masculinization score 1.5). Pelvic ultrasound revealed no Mullerian structures, a small right gonad with probable epidid...

Mosaicism Ratios of 45,X to 46,X IdicY Explained a Phenotype in a Case with Mixed Gonadal Dysgenesis

Hatano Megumi , Fukuzawa Ryuji , Hasegawa Yukihiro

Background: Patients with mixed gonadal dysgenesis (MGD), whose prototypical karyotype is 45,X/46,XY may manifest complications characteristic of Turner’s syndrome. We here present a 10-year-old male with MGD who had coarctation of aorta. At birth, he was found to have hypospadias, bifid scrotum and cryptorchidism. Chromosomal analysis of lymphocytes revealed a karyotype of 46,X idic Y (23)/45,X (7). Left gonadectomy was performed in infancy and the removed gonad showed s...

A Rare Case of Swyer Syndrome with Spontaneous Breast Development and Menstruation

Dundar Bumin Nuri , Sule Can P , Alparslan Caner , Akbay Sinem , Catli Gonul , Kelekci Sefa

Background: Swyer syndrome (46,XY pure gonadal dysgenesis) is a rare disorder, which is characterized by female phenotype, female internal genitalia and fibrotic and primitive gonads. Classically, breast development and menstruation are absent due to hypergonadotropic hypogonadism.Objective and hypotheses: To our knowledge, three cases of Swyer syndrome with spontaneous breast development have been reported so far. In these reports, breast development wa...

Phenotypic and Genotypic Variability of Patients with 5-α Reductase Type 2 Deficiency

Hu Kun , Krone Nils , Kirk Jeremy

Background: Steroid 5-α reductase type 2 (SRD5A2) deficiency is an rare inherited disorder resulting from mutations in the SRD5A2 gene, causing 46,XY DSD (Disorder of Sex Development). The mutated SRD5A2 enzyme can no longer convert testosterone to dihydrotestosterone, which is needed for virilisation of external genitalia.Objective and hypotheses: To describe the phenotype, investigations and management of SRD5A2 deficiency.<p class="a...

The Novel Mutation in the Steroidogenic Acute Regulatory Protein in 46,XY Case with Adrenal Insufficiency and Complete Sex Reversal

Gurbuz Fatih , Damla Kotan L , Mengen Eda , Topaloglu Ali Kemal , Yuksel Bilgin

Background: The steroidogenic acute regulatory protein (StAR) has been shown to be essential for steroidogenesis by mediating cholesterol transfer into mitochondria. Inactivating StAR mutations cause the typical clinical picture of congenital lipoid adrenal hyperplasia.Objective and hypotheses: We aimed to identify causative mutations in cases presenting with adrenal failure during early infancy.Method: Consecutive cases with adren...

A Challenging Diagnosis in Three 46,XY Females from Two Related Families

Mase Raffaella Di , Improda Nicola , Cerbone Manuela , De Martino Lucia , Capalbo Donatella , Baldazzi Lilia , Salerno Mariacarolina

Background: Mutations in the 17β-hydroxysteroid dehydrogenase (17βHSD 3) result in 46,XY disorder of sex development (DSD). Biochemical hallmark of 17βHSD 3 deficiency is a Testosterone/Androstenedione ratio (T/A ratio) <0.8. 17βHSD 3 mutations have been associated with a wide spectrum of phenotypes, ranging from under-virilized male to a female appearance of genitalia at birth. Indeed, 17βHSD 3 deficiency in prepubertal patients is often clinicall...

A Familial Case of Complete Androgen Insensitivity Syndrome

Maines Evelina , Piona Claudia , Morandi Grazia , Baldinotti Fulvia , Antoniazzi Franco , Gaudino Rossella

Background: Complete androgen insensitivity syndrome (CAIS) is a condition that results in the complete inability of the cell to respond to androgens and falls within the category of 46,XY disorder of sex development (DSD). CAIS is characterized by female external genitalia in a 46,XY karyotype individual with normal testis development but undescended testes and unresponsiveness to age-appropriate level of androgens. The typical presentation is primary amenorrhea in an adolesc...

A Case of 46,Y,dup(x)(p21.2p22.2) DSD Caused by Overexpressed DAX1

Takako Sasaki , Youko Izumi , Maki Fukami , Shuichi Yatsuga , Yasutoshi Koga

Introduction: DAX1 (dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1) plays an important role in developing the adrenal gland and testis during embryonic stage. On the other hand, overexpressed DAX1 causes 46,XY disorders of sex development (DSD), in which patients often have short stature, mental retardation, and telecanthus. Here we report a case of 46,Y,dup(X)(p21.2p22.2) DSD caused by overexpressed DAX1.Case ...

Background: Disorders of sexual differentiation (DSD) at birth is a serious defect often seen in endocrinology. Diagnosis must be early to ask an etiologic diagnosis, choose the sex of rearing and effectively treat the disease.Objective and hypotheses: Search etiologies of sexual ambiguities and clarify the phenotypic characteristics.Method: This is a retrospective study of 180 sexual ambiguities hospitalized. All patients underwen...
