Diagnostic and management considerations in pseudohypoaldosteronism type 1b

Pseudohypoaldosteronism type 1B is a rare autosomal recessive disorder caused by dysfunction of amiloride-sensitive epithelial sodium channels (ENaCs). We present the case of a neonate with cardiogenic shock after cardiac arrest due to profound hyperkalaemia. Genetic testing revealed a novel homozygous variant in SCNNIA. We review diagnostic considerations including the molecular mechanisms of disease, discuss treatment approaches and highlight the possible significance of the diversity of pulmonary ENaCs.

Hypomagnesemia with Secondary Hypoparathyroidism and Hypocalcemia due to Novel Variants in the Transient Receptor Potential Cation Channel Subfamily M Member 6 (TRPM6) Gene

HOMG1 (hypomagnesemia 1, intestinal) or hypomagnesemia with secondary hypocalcemia is a rare autosomal recessive disorder of magnesium metabolism, characterized by impaired magnesium absorption. This disorder may mimic other conditions presenting with neonatal seizures. Here, we report an infant diagnosed to have hypomagnesemia with secondary hypocalcemia due to novel variants in TRPM6 gene.

Triple A syndrome: a case report

Triple A syndrome is a rare autosomal recessive disorder characterised by alacrimia, achalasia and adrenal failure. It was first reported by Allgrove in 1978 and 100 cases have been reported worldwide. This case report concerns a 24-year-old woman who was referred for evaluation of dysphagia and was finally diagnosed as such a case. A high degree of suspicion enables all the components of this syndrome to be searched for, as early diagnosis can reduce the morbidity and mortality.

Spondylo-ocular Syndrome Due to a Novel Variant in XYLT2 in an Omani Patient

Spondylo-ocular syndrome (SOS) is a rare autosomal recessive disorder and affects primarily ocular and spinal tissues. This case report presents an Omani child with a novel homozygous variant, c.2070 G > A (p.Trp690Ter) in XYLT2 associated with SOS for the first time. Oman and other Middle East countries have a high consanguine marriage rate. Our case report will increase knowledge of SOS syndrome to be able to provide genetic diagnosis and counseling for other family members and families as well as prenatal diagnostics for the future pregnancies.

Severe haemoptysis in a 5 year old child with Kartagener’s syndrome: case report

Kartagener`s syndrome, a rare autosomal recessive disorder is a type of Primary Ciliary Dyskinesia (PCD) associated situs inversus, bronchiectasis, sinusitis and male infertility. We present a case of a 5-year-old girl who came with features of bilateral glue ear, recurrent sinusitis, recurrent hemoptysis and dextrocardia. She was diagnosed to have Kartagener`s syndrome and was evaluated for recurrent hemoptysis.

Papillon-Lefevre Syndrome: Challenge for Periodontal Management

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder associated with rapidly progressing periodontitis leading to premature loss of deciduous and permanent dentition and diffuse palmoplantar keratosis. Immunologic alterations, genetic mutations, and role of bacteria are some aetiologic factors. Patients present with early periodontal destruction, so periodontists play a significant role in diagnosis and management. This paper reports a case of Papillon- Lefevre syndrome with its clinical manifestations and challenges for periodontal management which was diagnosed in dental department.

Odontostomatological Findings in Heimler Syndrome: A Case Report

Heimler syndrome (HS) is rare autosomal-recessive disorder. [...]

Peeling skin syndrome: an investigational dilemma

<p><span lang="EN-IN">Peeling skin syndrome is a rare autosomal recessive disorder of cornification that starts either at birth or later in childhood, characterized by widespread painless peeling of the skin in superficial sheets. We report the case of a 13-year-old boy who presented with asymptomatic peeling of skin since birth. Sheets of skin were peeling from the neck, trunk and extremities following mild friction or rubbing, with sparing of palms and soles. The case is being reported due to its rarity.</span></p>

Multiple Nail Candidosis in a Child with APECED Syndrome

The APECED syndrome (autoimmune polyendocrinopathy, candidosis, ectodermal dystrophy) is a rare autosomal recessive disorder that develops in early childhood and results in tissue-specific multiorgan autoimmunity, leading to the hypofunction of multiple glands. Is clinically defined as the presence of at least two components of the classic triad of hypoparathyroidism, adrenal insufficiency, and mucocutaneous candidiasis. We report a case in a child, illustrating the importance of dermatological disorders.

Severe Infantile Transaldolase Deficiency

Transaldolase TALDO deficiency is a rare autosomal recessive disorder of the pentose phosphate pathway. It has variable presentations with poor outcome when present early in life. We present a young Saudi infant with a fatal early presentation of TALDO deficiency.
