First case report of turcot syndrome type 1 in Colombia.

ABSTRACT: Turcot syndrome is an autosomal recessive disorder clinically characterized by the occurrence of primary tumors of the central nervous system and adenomatous colonic polyps during the first or second decades of life, with a spectrum of clinical features such as "café-au-lait" spots, axillary freckling, and hyperpigmented spots. Currently its prevalence globally and in Colombia remains unknown. We present the case of a 20-year-old male with a clinical presentation of both glioblastoma multiforme and multiple adenomatous colonic polyps. The molecular genetics study revealed a mutation in Kras(Asp12) gene and altered expression of HMSH2 and HMSH6 proteins encoded by the DNA mismatch repair genes in two of the colonic polyps. Even though this clinical presentation may suggest a shorter survival rate, this patient is still alive after seven months of treatment. A literature review complements this report.

First Case Report of Prader-Willi-Like Syndrome in Colombia.

Project description:Background: Prader-Willi-like syndrome (PWLS) is believed to be caused by a variety of disruptions in genetic pathways both inside and outside of the genetic region implicated in PWS. By definition, PWLS does not demonstrate mutations in the 15q11-q13 region itself. It is a rare disorder whose clinical hallmarks include hypotonia, obesity, short extremities, and delayed development. This syndrome has been described in patients with 1p, 2p, 3p, 6q, and 9q chromosome abnormalities and in cases with maternal uniparental disomy of chromosome 14 and fragile X syndrome. Case presentation: In the present report, we describe a 9-year-old Colombian patient who demonstrated features of PWS and was ultimately diagnosed with PWLS after genetic analysis revealed a 14.97 Mb deletion of 6q16.1-q21. Conclusions: This is the first reported case of PWLS in Colombia and represents one of the largest documented 6q21 deletions.

Werner's Syndrome: Understanding the Phenotype of Premature Aging-First Case Described in Colombia.

Project description:Werner's syndrome (WS) is an autosomal recessive genetic disease, which is mainly characterized by scleroderma-like skin changes, juvenile cataracts, short stature, and signs of premature aging. We report a case of a 48-year-old male patient, who presents with cardinal signs of WS including high-pitched voice, sclerotic skin lesions mainly on feet, premature greying of scalp hair, bilateral cataracts, and "bird-like" facial appearance. In addition, the patient presents other clinical characteristics observed in patients with WS such as short stature, type 2 diabetes mellitus, hypogonadism, parental consanguinity, and a history of a sibling with similar clinical characteristics. WRN gene sequencing identified the homozygous pathogenic variant NM_00553.4: c.2581C>T (NP_000544.2: pGln861Ter). This is the first case of WS reported in the Colombian population. We report this case to avoid misdiagnosis of this infrequent condition and allow timely identification of potential complications associated with premature aging, especially malignancies, cardiovascular and metabolic diseases.

First documented case of Myhre syndrome in Romania: A case report.

Project description:Myhre syndrome is a rare genetic autosomal dominant connective tissue disorder, characterized by developmental delay, characteristic facial features, various bone and joint abnormalities, distinctive cardiovascular, ophthalmological and ear, nose and throat (ENT) manifestations, in association with mild to moderate intellectual disability and autism or autism spectrum disorder-like behaviour. The diagnosis of Myhre syndrome is established corroborating the clinical findings with SMAD4 heterozygous mutation identified in the majority of the patients. SMAD4 gene mutations result in abnormal TGF-β signalling in several cell types, which affects the development of several body systems and leads to the specific phenotype of Myhre syndrome. We herein report the case of an 18-year-old female patient who was diagnosed at the age of 17 years with Myhre syndrome, the first documented case of this syndrome in Romania. Sequence analysis of protein-coding genes using whole-exome analysis identified a 'de novo', heterozygous missense variant of SMAD4, c.1498A>G, p. (Ile500Val), which is pathogenic for Myhre syndrome. Although this condition is rare, a series of particularities were identified in the present case, consisting of severe allergic reactions, recurrent ENT tumour development and delayed dental eruption, which have not been described in Myhre syndrome to date, to the best of the authors' knowledge.

First case report of Nager syndrome patient from Georgia.

Project description:Nager syndrome (MIM #154400) is a rare acrofacial dysostosis syndrome predominantly characterized by malformations in craniofacial and preaxial limb bones. Most cases are sporadic and present with significant clinical heterogeneity. Although autosomal recessive and autosomal dominant modes of inheritance have been reported, most cases of Nager syndrome are spontaneous. Heterozygous variants in SF3B4 on chromosome 1q21 are found in approximately 60% of patients. Here, we report a first patient from Georgia diagnosed with Nager syndrome with detailed description of its clinical manifestations and diagnosis.

Allgrove syndrome: Case report of 18 years old male:the first case report from Syria.

Project description:Triple A syndrome 3A (Allgrove syndrome) is a rare autosomal recessive multiorgans dysfunction characterized by alacrima, achalasia which is the absence of esophageal muscle peristalsis and lower sphincter failure to relax and adrenal insufficiency. About third of patient additional features like neurological and autonomic manifestations reported (making the syndrome 4A), the spectrum of neurological symptoms varies including gait disturbances, parkinsonism, muscle wakeness, mental retardation, peripheral sensory and motor neuropathy. Here we reported A 18 years old male, who had postnatal recurrent conjunctivitis so alacrima was diagnosed, in the sventh years he developed achalasia signs; dysphagia and regurgitation and laparscopic surgical myotomy and fundoplication were done, when he became 16 he presented to our clinic for poor appetite, weight loss,and failure to thrive. Assessment of ACTH, cortisol, ACTH stimulation test confirmed he had adrenal insufficiency and physical examination showed he had foots deformity due to muscular atrophy caused by neuropathy.treatment performed by managing symptoms of the condition(replacement of glucocorticoids, surgical correction of achalasia, artificial tears).The follow-up was over a period of 6 months and we noted a great improvement of patient's condition.

Autoimmune Polyglandular Syndrome Type 1: a case report.

Project description:BackgroundMutations of the autoimmune regulator gene (AIRE), located on chromosome 21q22.3, are recognized as the cause of a rare monogenic organ-specific autoimmune disorder called autoimmune polyglandular syndrome type 1 (APS-1). Three major components of this syndrome include chronic mucocutaneous candidiasis (CMC), hypoparathyroidism, and adrenocortical failure.Case presentationWe report a 19-year-old girl, who was born in an Iranian Muslim family with a clinical diagnosis of APS-1. To identify the causative mutation, a direct sequencing of the entire AIRE gene sequence was performed by Sanger sequencing method. Three distinct variants were discovered, including c.1095 + 2 T > A, c.1197 T > C (rs1800521) and c.1578 T > C (rs1133779), in intron 9, exons 10 and 14 of the AIRE gene, respectively.ConclusionsTo the best of our knowledge, this is the first report of an Iranian Muslim APS-1 patient with combination of these variations. In addition, the effect of c.1095 + 2 T > A mutation on AIRE mRNA expression was reported for the first time. This study expands the diversity of variants that could cause APS-1. More genetic studies are required to determine the exact frequency of these variants and their diagnostic significance.

First case recognized as autoimmune polyglandular syndrome type 2 with myasthenia gravis in Palestine: A case report and literature review.

Project description:BackgroundMyasthenia gravis is an organ specific autoimmune disorder that is potentially serious but treatable. It is characterized by fatigability of the voluntary muscles and weakness caused by antibodies against the nicotinic acetylcholine receptor (AChR) on the postsynaptic membrane at the neuromuscular junction.Sometimes, and in very rare cases, it can be associated with other autoimmune conditions in a so called autoimmune polyglandular syndrome type 2, which consists mainly of autoimmune adrenal insufficiency (Addison's disease) with autoimmune thyroid disease and/or type 1 diabetes mellitus.Case presentationWe describe a case of a 47-year-old male patient presenting with weakness, difficulty swallowing (mainly liquids) and dysarthria. He was discovered to have low cortisol and TSH levels with high T4 and T3. These findings lead to the suspicion of a more complex disease process and through a thorough research of literature we discovered an association between myasthenia gravis and autoimmune polyglandular syndrome specifically type 2 which fits with our patients' presentation.ConclusionIn any autoimmune disease, it is important to keep in mind associations and susceptibilities to other autoimmune processes and syndromes in order to reach a correct diagnosis and treatment preventing life threating events.

Silent sinus syndrome (First Case Report, Saudi Arabia with recommendation).

Project description:IntroductionSilent sinus syndrome is a rare disorder that presents a diagnostic challenge, most of the patients with this syndrome present with ophthalmological complaints without any nasal sinus symptoms, and it has a painless course and slow development. The syndrome can be diagnosed clinically and confirmed radiologically, and CT imaging is considered the gold standard for its diagnosis. The classical radiographic findings are opacification and collapse of the sinus walls. Functional endoscopic sinus surgery (FESS) is the standard gold treatment of choice to arrest the progression of the disease.Presentation of caseA case report of a 37-years-old-female who was complaining of severe throbbing pain since 2009, is presented here where the diagnosis of SSS was obtained in 2018, this delay in diagnosing the situation had affected the patient lifestyle tremendously.DiscussionAccordingly, knowledge of the signs and features of SSS can result in an accurate diagnosis. Suspected cases of silent sinus syndrome require prompt ear, nose, and throat referral for consideration of definitive diagnosis and surgical management. Nasal endoscopy and clinical evaluation are also essential for the diagnosis.ConclusionOur recommendation is to consider SSS as a differential diagnosis for patients with spontaneous enophthalmos and hypoglobus, even in the absence of maxillary sinus opacification. Moreover, encourage all the specialists in the medical and the dental field to communicate well together in cases like this.

DRESS syndrome in response to Denosumab: First documented case report.

Project description:Denosumab is an antiresorptive drug targeting RANK ligand, currently licensed for postmenopausal and male osteoporosis, bone loss associated with hormone ablation in men with prostate cancer and with systemic glucocorticoid treatment, and also used in oncology for the treatment of bone metastases and unresectable giant cell tumour of bone. When used for the treatment of osteoporosis or bone loss the drug is usually well-tolerated with non-specific musculoskeletal pain being the most common side effect. However denosumab has been associated with some dermatological manifestations including dermatitis, eczema, pruritus and, less commonly, cellulitis. All these side effects are generally mild and self-limiting. We hereby report the first documented case of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome following denosumab administration. DRESS syndrome is an extremely rare but potentially life-threatening hypersensitivity reaction. The syndrome should be considered in patients who present with new rash, eosinophilia and systemic organ dysfunction, especially when associated with new medications. Notably it has been previously reported in patients with osteoporosis treated with strontium ranelate but it has never been linked to any other antiosteoporotic drugs. Since the clinical manifestations of DRESS syndrome can span over a period of several months the diagnosis can frequently be quite difficult and it can become even more challenging in people taking denosumab and other drugs given in period doses, as both clinicians and patients are less likely to link the symptoms to the medication. Better recognition of DRESS syndrome is therefore needed, as well as awareness of the possibility of this reaction to occur in patients taking denosumab.

First reported adult patient with TARP syndrome: A case report.

Project description:TARP syndrome (talipes equinovarus, atrial septal defect, Robin sequence, and persistence of the left superior vena cava) is a rare X-linked syndrome often resulting in pre- or post-natal lethality in affected males. In 2010, RBM10 was identified as the disease-causing gene, and we describe the first adult patient with TARP syndrome at age 28 years, hereby expanding the phenotypic spectrum. Our patient had Robin sequence, atrial septal defect, intellectual disability, scoliosis, and other findings previously associated with TARP syndrome. In addition, he had a prominent nose and nasal bridge, esotropia, displacement of lacrimal points in the cranial direction, small teeth, and chin dimple, which are the findings that have not previously been associated with TARP syndrome. Our patient was found to carry a hemizygous c.273_283delinsA RBM10 mutation in exon 4, an exon skipped in three of five protein-coding transcripts, suggesting a possible explanation for our patient surviving to adulthood. Direct sequencing of maternal DNA indicated possible mosaicism, which was confirmed by massive parallel sequencing. One of two sisters were heterozygous for the mutation. Therefore, we recommend sisters of patients with TARP syndrome be carrier tested before family planning regardless of carrier testing results of the mother. Based on our patient and previously reported patients, we suggest TARP syndrome be considered as a possible diagnosis in males with severe or profound intellectual disability combined with septal heart defect, and Robin sequence, micrognathia, or cleft palate.
