Ellis Van Creveld Syndrome

Ellis-van Creveld syndrome (EVC) is a very rare mesenchymal- ectodermal dysplasia. This was first described in 1940 by Richard W. B. Ellis and Simon van Creveld.This rare condition is inherited as an autosomal recessive trait with variable expression. It is also known as mesoectodermal dysplasia or chondroectodermal dysplasia. The main features of this syndrome are short ribs, polydactyly, growth retardation, and ectodermal and heart defects. It is a rare disease with approximately 150 cases reported worldwide. It was found to be more common among the Amish. But sporadic cases have been reported from all over the world including India. The generalized dysplasia of endochondral ossification is because of   in a novel gene on chromosome 4p16. Mutations of the EVC1 and EVC2 genes, located in head to head configuration on chromosome 4p16 have been identified as a causative factor

Congenital hepatic fibrosis is a rare condition characterized by extensive fibrosis of liver but with preserved normal lobular architecture inherited as autosomal recessive trait. We report a 19 year-old-female admitted to Bangabandhu Sheikh Mujib Medical University with the complaints of lump in upper abdomen since last 13 years and episodes of fever and abdominal pain for same duration. She was diagnosed with hepatic TB on hepatic histology. Congenital hepatic fibrosis is a rare cause of portal hypertension that presents during childhood. Prognosis of congenital hepatic fibrosis is good. Life threatening events in these patients are related with variceal bleeding and episodes of cholangitis. Owing to relatively good liver function these patients tolerate portosystemic shunt surgeries quite well.Though rare, congenital hepatic fibrosis should be included in the differential diagnosis of portal hypertension in early life.

Rare Autosomal Recessive Disease

Ellis Van Creveld, a syndrome comprising of chondrodysplasia, bilateral polydactyly of the hands with skeletal abnormalities, and congenital heart defect is a rare autosomal recessive disease. The prevalence of the disease in the world is 1/6000–20,000 newborns. In the Indian population, it is difficult to estimate the exact prevalence of the disease but, it is mostly seen in the Amish population. The cardinal features are short stature, dysplastic nails and teeth, polydactyly, narrow chest, and heart defects. The crucial differentials are Jeune dystrophy, Weyers syndrome, and McKusick-Kaufman syndrome. Here, we report a neonate, born of a non-consanguineous marriage with a syndromic appearance consisting of a bell-shaped chest, polydactyly, natal teeth, and single atrium. Prognosis is related to respiratory and heart defects in the early neonatal period.

Ellis Van Creveld Syndrome

Abstract Background: Ellis-van Creveld syndrome (EVC) is a rare autosomal recessive disorder, the features of the syndrome are: chondral and ectodermal dysplasia characterized by short ribs, polydactyly, growth retardation resulting in dwarfism, teeth and craniofacial abnormalities and heart defects (mostly endocardial cushions and atrial septal defects). Case presentation: We describe the first case of COVID-19 infection in a 24-years-old girl, diagnosed with EVC syndrome. The patient suffered only from a mild illness, she remained stable with normal saturation without need of neither respiratory support nor specific therapy and she was rapidly discharged.Conclusions: This case appraises the pathophiosiologic interplay between different specific prognostic variable in a syndromic patient with congenital heart disease and COVID-19.

Abstract Ellis-van Creveld syndrome (EVC) is a genetic disorder that was first described by Richard Ellis and Simon van Creveld in 1940. EVC is a rare autosomal recessive disease resulting from a genetic defect located in chromosome 4p16. The name chondroectodermal is used as it affects both the skeleton (chondro) and the skin (ectoderm). The four principal characteristics are chondrodysplasia, polydactyly, ectodermal dysplasia and congenital heart defects. The patients have small stature, short limbs, fine sparse hair and hypoplastic nails. The orofacial manifestations include multiple gingivolabial musculofibrous frenule, dental anomalies like hypodontia associated with malocclusion. This entity can be diagnosed at any age, even during pregnancy. The differentiation should be made between Asphyxiating Thoracic Dysplasia (Jeune syndrome) and other orofaciodigital syndromes. A multidisciplinary approach is required to manage this condition. We are reporting a rare clinical entity of chondroectodermal dysplasia with classical signs affecting siblings who reported to the Department of Oral Medicine and Radiology with review of its literature.

Introduction: Ellis-van Creveld (EVC) syndrome is an uncommon genetic disease that can be diagnosed at any age. Observation: A case of EVC syndrome was reported in a young 3-year-old female patient presenting chondroectodermal dysplasia, polydactyly, congenital heart defects, damage to the oral mucosa and numerous dental alterations (number, form and structure). Oral management consists of teaching oral hygiene and the prophylactic filling of dental cracks. Discussion: EVC is an autosomal recessive disease. Its diagnosis is only based on clinical features and genetic studies. Conclusion: Dentists should be aware of this syndrome to avoid a late diagnosis and to facilitate a multidisciplinary management.

Genetic And Environmental Factors

Congenital missing permanent second molar is an extremely rare condition. Non syndromic mandibular second molar agenesis associated with other anomalies has occasionally been reported in literature, but isolated sporadic cases are rarely observed. Number of interactions between genetic and environmental factors during the process of tooth development might be the causative etiology for agenesis. This report presents an isolated case of hypodontia with absence of bilateral mandibular second molar agenesis in a healthy 18 year old female patient is presented and literature review on prevalence of most missing teeth with incidence of missing second molar in various regions of the world and in various regions of Indian continent is presented. No such case has been reported in Indian literature so far.

Abstract Sialidosis, a rare autosomal recessive disorder, is caused by a deficiency of NEU1 encoded enzyme alpha-N-acetyl neuraminidase. We report a premature male with neonatal-onset type II sialidosis which was associated with left ventricular dysfunction. The clinical presentation and subsequent progression which culminated in his untimely death at 16 months of age are succinctly described. Early-onset cardiovascular involvement as noted in this patient is not well characterised. The case report is supplemented by a comprehensive review of the determinants, characteristics, and the clinical course of cardiovascular involvement in this rare condition.

Autosomal Recessive Manner

Canine pituitary dwarfism in German Shepherd and related dog breeds has been reported to be associated with a 7-bp deletion mutation in intron 5 of the LHX3 gene. This mutation is transmitted as an autosomal recessive trait that results in dwarf dogs with significantly smaller stature and abnormal haircoat, and potentially early death. Phenotypically, affected adult dogs are proportionally dwarfs. These dwarfs also have a soft, woolly puppy coat that fails to transition into the typical adult hair coat, and marked hair loss occurs in some dogs. We report a similar manifestation of dwarfism in Tibetan Terriers with the same LHX3 mutation. Dwarf Tibetan Terrier puppies were born physically normal but failed to gain weight or to grow at the same rate as their normal littermates. The 7-bp deletion mutation of the LHX3 gene was identified in both alleles of 3 Tibetan Terrier dwarfs from 3 litters, which were biologically related. All parents of these dogs are carriers, confirming transmission of dwarfism in an autosomal recessive manner. Recognition and detection of this mutation will help in guiding future breeding plans to eventually eliminate this trait from Tibetan Terriers.

1. Beginning with a single propositus, who had been previously diagnosed at the age of 10 as suffering from trimethylaminuria (fish-odour syndrome), both her parents and two sisters were investigated biochemically with respect to their ability to N-oxidize trimethylamine (TMA), both when derived from the diet and when administered exogenously. 2. Both the propositus and a second sister were markedly deficient in their ability to N-oxidize TMA, both when derived from the diet and when given as such; furthermore, both siblings readily developed the symptoms of fish-odour syndrome as characterized by a strong objectionable breath and body odour shortly after the oral administration of TMA (300 mg). 3. At this dose level of TMA, neither of the parents nor the third sister showed any evidence of impaired N-oxidation ability nor did they experience any ‘fish-odour’ symptoms. 4. With an oral challenge of 600 mg of TMA, both the parents showed a clear impairment of N-oxidation capacity which was not seen in six healthy unrelated volunteers. Both parents experienced a fish-odour syndrome at this level of TMA challenge. 5. The family data support the hypothesis that trimethylaminuria is an inborn error in the ability to N-oxidize TMA which is inherited as an autosomal recessive trait. Furthermore, experience with this family suggests that an oral challenge dose with 600 mg of TMA may be used to identify carriers of the condition.

Clinical Phenotyping

Hereditary motor and sensory neuropathy with agenesis of the corpus callosum (HMSN/ACC) is a rare autosomal recessive condition characterised by early-onset severe progressive neuropathy, variable degrees of ACC and cognitive impairment. Mutations in SLC12A6 (solute carrier family 12, member 6) encoding the K+–Cl- transporter KCC3 have been identified as the genetic cause of HMSN/ACC. We describe fraternal twins with compound heterozygous mutations in SLC12A6 and much milder phenotype than usually described. Neither of our patients requires assistance to walk. The female twin is still running and has a normal intellect. Charcot-Marie-Tooth Examination Score 2 was 8/28 in the brother and 5/28 in the sister. Neurophysiology demonstrated a length-dependent sensorimotor neuropathy. MRI brain showed normal corpus callosum. Genetic analysis revealed compound heterozygous mutations in SLC12A6, including a whole gene deletion. These cases expand the clinical and genetic phenotype of this rare condition and highlight the importance of careful clinical phenotyping.
