Background: Allgrove syndrome is a multisystem disorder first described in 1978 and is classically associated with esophageal achalasia, alacrima, and adrenal insufficiency. Allgrove syndrome is caused by homozygous and/or compound heterozygous mutations on Chromosome 12q13, designated as "AAA" (Achalasia, Addisonianism Alacrima). AAA encodes the protein ALADIN (Alacrima, Achalasia, aDrenal Insufficiency Neurologic disorder), a member of the nuclear porin family forming the nuclear pore complex. Read More

Hypokalemia Associated With a Claudin 10 Mutation: A Case Report.

Am J Kidney Dis 2018 Oct 25. Epub 2018 Oct 25.

Division of Nephrology, Department of Pediatrics, NYU Langone Health, New York, NY. Electronic address:

Hypokalemia of renal origin can arise from genetic abnormalities in a variety of transporters or channel proteins that mediate tubular handling of potassium. Recently, mutations in claudin 10 have been documented in patients with hypokalemia in association with a range of other electrolyte abnormalities and skin and sweat gland manifestations. We report a 12-year-old Hispanic boy who presented with anhydrosis, aptyalism, alacrima, hypokalemia, and hypocalciuria, in whom we detected a homozygous mutation in the claudin 10 gene. Read More

Atypical Presentation of Adrenocortical Insufficiency with Anorexia and Jaundice.

Am J Case Rep 2018 Jun 18;19:705-709. Epub 2018 Jun 18.

Department of Gastroenterology, Yuedong Hospital of the Third Affiliated Hospital of Sun Yat-sen University, Meizhou, Guangdong, China (mainland).

BACKGROUND Adrenal insufficiency is mainly due to insufficient adrenal corticosteroid hormones secretion by the adrenal cortex, which leads to clinical manifestations such as weakness, weight loss, hyperpigmentation, hypotension, and vomiting. However, the clinical manifestations of adrenocortical insufficiency may be atypical: anorexia, ascites, impaired liver function, and alacrima have been reported. Jaundice and anorexia presenting together in the same patient as the main symptoms are rare. Read More

Allgrove or triple A syndrome is a rare autosomal recessive disorder that can present with a variable range of multi-system manifestations, including optic atrophy, cerebellar ataxia, upper and lower motoneuron signs and various neuropathic abnormalities. These cases are a diagnostic challenge, particularly when the eponymous combination of achalasia, Addisonianism and alacrima is incomplete. Therefore, it is in the differential diagnosis for multisystem conditions and should be known to pathologists who diagnose disorders of skeletal muscle. Read More

Unlabelled: Triple A syndrome (alacrima, achalasia, adrenal failure, progressive neurodegenerative disease) is caused by mutations in the AAAS gene which encodes the protein alacrima achalasia adrenal insufficiency neurologic disorder (ALADIN). Our investigation suggests that low bone mineral density (BMD) for age/osteoporosis could be a common but overlooked symptom of unexplained etiology in this rare multisystemic disease.

Mutations in HAO1 encoding glycolate oxidase cause isolated glycolic aciduria.

J Med Genet 2014 Aug 4;51(8):526-9. Epub 2014 Jul 4.

Division of Pediatric Nephrology, Shaare Zedek Medical Center, Jerusalem, Israel.

Background: The primary hyperoxalurias are a group of recessive kidney diseases, characterised by extensive accumulation of calcium oxalate that progressively coalesces into kidney stones. Oxalate overproduction is facilitated by perturbations in the metabolism of glyoxylate, the product of glycolate oxidation, and the immediate precursor of oxalate. Glycolic aciduria associated with hyperoxaluria is regarded as the hallmark of type 1 primary hyperoxaluria. Read More

Blepharophimosis syndrome with absent tear production.

Ophthalmic Plast Reconstr Surg 2015 May-Jun;31(3):e62

*Oregon Health and Science University, Casey Eye Institute; and †EyeHealth Northwest, Portland, Oregon, U.S.A.

The purpose of this report was to present a case of congenital alacrima in a patient with blepharophimosis-ptosis-epicanthus inversus syndrome (BPES). A 9-month-old boy presented with characteristic clinical findings of BPES confirmed by genetic testing. On further history taking and evaluation, the patient was noted to have no tear production, despite clinically present palpebral lobes of the lacrimal glands. Read More

Surgical treatment of infantile achalasia: a case report and literature review.

Pediatr Surg Int 2014 Jun 26;30(6):677-9. Epub 2014 Mar 26.

Division of Pediatric Surgery, Michael E DeBakey Department of Surgery, Baylor College of Medicine, 6701 Fannin Street Suite 1210, Houston, TX, 77030, USA.

Allgrove syndrome is a rare genetic disorder typically manifested by alacrima, achalasia, and adrenal insufficiency, and is one of the rare causes of achalasia in infants. While the gold standard for achalasia treatment in adults is an esophageal myotomy with fundoplication, a standard treatment for infantile achalasia remains undetermined due to the low number of reported cases and rarity of the disease in this age group. We report a 7. Read More

Mutations in NGLY1 cause an inherited disorder of the endoplasmic reticulum-associated degradation pathway.

Genet Med 2014 Oct 20;16(10):751-8. Epub 2014 Mar 20.

1] Center for Human Genome Variation and Department of Medicine, Duke University School of Medicine, Durham, North Carolina, USA [2] Department of Molecular Genetics and Microbiology, Duke University School of Medicine, Durham, North Carolina, USA.

Purpose: The endoplasmic reticulum-associated degradation pathway is responsible for the translocation of misfolded proteins across the endoplasmic reticulum membrane into the cytosol for subsequent degradation by the proteasome. To define the phenotype associated with a novel inherited disorder of cytosolic endoplasmic reticulum-associated degradation pathway dysfunction, we studied a series of eight patients with deficiency of N-glycanase 1.

Methods: Whole-genome, whole-exome, or standard Sanger sequencing techniques were employed. Read More

"A" motor neuron disease.

J Neurol Sci 2014 Jan 8;336(1-2):251-3. Epub 2013 Oct 8.

Department of Neurology, Post Graduate Institute of Medical Education and Research, Chandigarh 160012, India. Electronic address:

Importance: Allgrove syndrome is a rare autosomal recessive disorder characterised by achalasia, alacrima, adrenal insufficiency, autonomic dysfunction and amyotrophy. The syndrome has been described in childhood and adult presentation, as in our case, is very rare. There is a considerable delay in diagnosis due to lack of awareness about the syndrome. Read More
