Background: The investigation of patients with 46,XY DSD is often difficult, with no definitive diagnosis in more than 50% of cases investigated. We describe a new mutation of MAMLD1 in a patient with 46,XY DSD who also showed an alteration in the NR5A1 gene.Case report: A 5-year-old boy was referred to our clinic for DSD. He was born to non-consanguineous parents and was diagnosed with ambiguous genitalia at birth but had not been previously investigate...

Background: Short stature and gonadal dysgenesis are the two characteristic clinical features of Turner syndrome (TS), but multiple systems may be affected.Aims: To evaluate TS prevalence in girls presenting with short stature; and to establish a correlation between karyotype and associated features.Subjects and methods: Retrospective study of all patients diagnosed with TS (December 2007–March 2013).Res...

Background: The steroidogenic enzyme aromatase is encoded by the CYP19A1 gene. Aromatase activity is required for estrogen biosynthesis from androgen precursors in the ovary and several extragonadal tissues. The role of aromatase and thus estrogens for human biology is best illustrated by disease states, both deficiency and excess which might be caused by genetic disorders.Aim: A novel deletion-insertion mutation spanning from intron 10 to the 3...

Background: Fanconi–Bickel syndrome (FBS) is a rare glycogen storage disease characterized by hepato-renal glycogen accumulation, severe renal tubular dysfunction and impaired glucose and galactose metabolism. We present the case histories of two sisters who were diagnosed with FBS.Case reports: The proband, Lina, was referred to our clinic for growth retardation and abdominal distention aged 27 months. She is the 4th child of consanguineous parents...

Background: The i.v. GnRH test remains the gold standard for the diagnosis of central precocious puberty (CPP). Unfortunately however, GnRH is expensive and is not available worldwide. GnRH analogues have been used as an alternative, but their place is not established, while very few studies have compared between the two tests.Objective: To compare the effects of GnRH and Triptorelin on gonadotrophin secretion in patients with sexual precocity and hence ...

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.Objective and hypotheses: To est...
