Atypical Presentation of Six Patients with Mutations in the Side Chain Cleavage Enzyme CYP11A1

Chan Li , Huebner Angela , Spoudeas Helen , Cheetham Tim , Metherell Louise

Background: Mutations in the side chain cleavage enzyme, (CYP11A1) cause congenital adrenal insufficiency, with complete or partial 46XY sex reversal. The disorder manifests with adrenal and gonadal insufficiencies along with derangements of the renin/angiotensin system.Objective and hypotheses: To obtain a genetic diagnosis in six patients with adrenal insufficiency of unknown aetiology. Patients 1 and 2 are sisters with ACTH resistance, having...

Background: Two siblings of non-consanguineous parents presented with FGD, demonstrated by ACTH resistance with glucocorticoid but not mineralocorticoid deficiency. The proband presented at 21 months, unresponsive with hypoglycaemia (BGL 1.5 mmol/l). Endocrine evaluation subsequent to resuscitation indicated adrenal insufficiency with elevated ACTH. Hydrocortisone therapy was commenced. A sibling, 4 years younger than the proband had a short Synacthen test (SST) performed on d...

Clinical and Genetic characterization of primary adrenal insufficiency in Sudanese children

A. Musa Salwa , A. Abdullah Mohamed , S. Hassan Samar , Qamar Younus , Hall Charlotte , Maitra Saptarshi , V Maharaj Avinaash , Mariela Marroquin Ramirez Lucia , Read Jordan , Smith Christopher , F Chan Li , A Metherell Louise

Background: Primary adrenal insufficiency (PAI) in children is an uncommon condition. Diagnosis is usually challenging especially in resource limited settings where facilities for antibodies and genetic testing are constrained. Many genetic etiologies have been reported in children with PAI due to congenital adrenal hyperplasia (CAH) and Allgrove syndrome are the commonest identified genetic causes to date in Sudan. Studies from Africa are rare and here we des...

Rare Genetic Etiology of Primary Adrenal Insufficiency in Children; Clinical and Genetic Characterization of a Large Sudanese Cohort

Musa Salwa , Abdullah Mohamed , Hassan Samar , Fauzi Luqman , Qamar Younus , Hall Charlotte , Maitra Saptarshi , Maharaj Avinaash , Mariela Marroquin Ramirez Lucia , Read Jordan , F Chan Li , A Metherell Louise , J Smith Chris

Background: Studies of Primary Adrenal Insufficiency (PAI) from Africa are scanty while in Sudan, congenital adrenal hyperplasia (CAH) followed by Triple A syndrome are the commonest reported genetic etiologies in children. Diagnosis is challenging, especially in resource limited settings where presentation can mimic common childhood diseases and facilities for biochemical and genetic testing are restricted.Patients & Methods...

Introduction: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires appropriate diagnosis and treatment. The most common cause of PAI is congenital adrenal hyperplasia (CAH), but other well-established aetiologies include metabolic and autoimmune disorders, and physical damage. Mutations in more than 30 genes have now been associated with PAI, with considerable biochemical and phenotypic overlap. It is therefore importan...
