O-43: Mutations in NR5A1 Associated withOvarian Insufficiency
Background: The genetic causes of nonsyndromic ovarian insufficiency are largely unknown. A nuclear receptor, NR5A1 (also called steroidogenic factor 1), is a key transcriptional regulator of genes involved in the hypothalamic–pituitary–steroidogenic axis. Mutation of NR5A1 causes 46,XY disorders of sex development, with or without adrenal failure, but growing experimental evidence from studies...
متن کاملA female with 46,XY Disorder of Sexual Development with normal SRY gene sequence: A case report
Background: Disorders of sex development (DSD) are a medical condition that affects the normal process of sexual Various of the genes needed for gonad development have been identified by investigation of patients with disorders sex development (DSD).Phenotypes of patients with 46,XY DSD range from atonalism in female phenotype with complete external genitalia to male phenotype with testicular...
متن کاملManagement of children with disorders of sex development: 20-year experience in southern Thailand.
BACKGROUND Disorders of sex development (DSD) is a group of sexual differentiation disorders resulting in genital anomalies with defects in gonadal hormone synthesis and/or incomplete genital development. These conditions result in problems concerning the sex assignment of the child. This study aims to describe the clinical features, diagnosis and management of children with DSD in southern Tha...
متن کاملGenetic Screening of Iranian Patients with 46,XY Disorders of Sex Development
Background: Disorders of sex development (DSDs) belong to uncommon pathologies and result from abnormalities during gonadal determination and differentiation. Various gene mutations involved in gonadal determination and differentiation have been associated with gonadal dysgenesis. Despite advances in exploration of genes and mechanisms involved in sex disorders, most children with severe 46,XY ...
متن کاملFemale with 46, XY karyotype
Disorders of sex development (DSD) are congenital conditions characterized by atypical development of chromosomal, gonadal, and phenotypic sex. 46, XY DSD can result from disorders of testicular development or disorders of androgen synthesis/action. Prophylactic gonadectomy should be considered in patients with 46, XY DSD because of the increased risk of gonadal malignancy. We report two rare c...
متن کاملSubmicroscopic copy-number variations associated with 46,XY disorders of sex development
BACKGROUND Mutations in known causative genes and cytogenetically detectable chromosomal rearrangements account for a fraction of cases with 46,XY disorders of sex development (DSD). Recent advances in molecular cytogenetic technologies, including array-based comparative genomic hybridization (aCGH) and multiplex ligation-dependent probe amplification (MLPA), have enabled the identification of ...
