Recently, knowledge about the molecular genetic of male infertility has increased. However, in many cases, the etiology of infertility remains unknown. The Cancer/testis antigen: Fetal and Adult Testis Expressed (FATE-1), mainly expressed in human testis has been described two decades ago for his potential role in male infertility. FATE-1 is located on the X chromosome, contains a putative SF1 binding site and is co-expressed with SRY in human fetal testis. To date, only few d...

Background: Steroid 11-β hydroxylase deficiency is the second most frequent cause of adrenal hyperplasia (CAH) with autosomal recessive inheritance. Girls have importantly virilized external genitalia at birth, and boys display precocious pseudopuberty. Unlike others enzymatic deficiency involved in CAH, there is no salt wasting during infancy but patients develop hypertension. Because of more than 90% of homologous sequence between CYP11B1 gene ...

Introduction: Disorders of sexual development (DSD) encompass a complex group of conditions characterized by a discrepancy between phenotypic and chromosomal sex, sometimes associated with impaired sex steroid synthesis or hormone action. DSD can be detected prenatally; however, establishing their etiology remains challenging. Our objective is to identify steroid profiles that could guide prenatal molecular analyses for diagnosis and perinatal care.<p clas...

Background: Steroidogenic Factor 1 (SF-1), encoded by NR5A1 (Nuclear receptor subfamily 5 group A member 1) gene, is a transcriptional factor that is primordial for adrenal and gonadal organogenesis. Pathogenic variants of NR5A1 are responsible for a wide spectrum of phenotypes with autosomal dominant inheritance, from adrenal insufficiency to gonadal dysgenesis and oligospermia-azoospermia in 46,XY patients.Obj...

Background: Triple A syndrome (AAAS, OMIM#231550) is a very rare inherited disease characterized by the association of chronic adrenal insufficiency, achalasia, alacrima and central and peripheral neurological disorders. It is caused by mutations in the AAAS gene which encodes the nuclear pore complex scaffolding protein ALADIN. The relative prevalence and genotype of AAAS in the Maghreb countries has not been ascertained.Objecti...
