MASA Syndrome in Twin Brothers: Case Report of Sixteen-Year Clinical Follow Up
Paediatr Croat. 2014;58:286-90 PRIKAZ BOLESNIKA / CASE REPORT www.paedcro.com http://dx.doi.org/10.13112/PC.2014.50 MASA syndrome in twin brothers: case report of sixteen-year clinical follow up Matilda Kovač Šižgorić1, Zlatko Sabol1, Filip Sabol2, Tonći Grmoja3, Svjetlana Bela Klancir1, Zdravka Gjergja1, Ljiljana Kipke Sabol1 MASA syndrome (OMIM 303350) is a rare X-linked recessive neurologic disorder, also called CRASH syndrome, spastic paraplegia 1 and Gareis-Mason syndrome. The acronym MASA describes four major signs: Mental retardation, Aphasia, Shuffl ing gait and Adducted thumbs. A more suitable name for this syndrome is L1 syndrome because the disorder has been associated with mutations in the neuronal cell adhesion molecule L1 (L1CAM) gene. The syndrome has severe symptoms in males, while females are carriers because only one X chromosome is aff ected. The aim of this report is to show similarities and diff erences in clinical manifestations between twins with the L1CAM gene mutation and to emphasize the importance of genetic counseling. Our patients were dizygotic twins born prematurely at 35 weeks of gestation. Pregnancy was complicated with early bleeding and gestational diabetes. Immediately after birth, hypertonia of lower extremities was observed in both twins. Sixteen-year clinical follow up showed spastic paraparetic form with shuffl ing gait, clumsiness, delayed speech development, lower intellectual functioning at the level of mild to moderate mental retarda- tion, primary nocturnal enuresis, behavioral and sleep disorder (more pronounced in the second twin). Magnetic resonance imaging of the brain showed complete agenesis of the corpus callosum, complete lack of the anterior commissure, and internal hydrocephalus. -
Cardiomyopathy Precision Panel Overview Indications
Cardiomyopathy Precision Panel Overview Cardiomyopathies are a group of conditions with a strong genetic background that structurally hinder the heart to pump out blood to the rest of the body due to weakness in the heart muscles. These diseases affect individuals of all ages and can lead to heart failure and sudden cardiac death. If there is a family history of cardiomyopathy it is strongly recommended to undergo genetic testing to be aware of the family risk, personal risk, and treatment options. Most types of cardiomyopathies are inherited in a dominant manner, which means that one altered copy of the gene is enough for the disease to present in an individual. The symptoms of cardiomyopathy are variable, and these diseases can present in different ways. There are 5 types of cardiomyopathies, the most common being hypertrophic cardiomyopathy: 1. Hypertrophic cardiomyopathy (HCM) 2. Dilated cardiomyopathy (DCM) 3. Restrictive cardiomyopathy (RCM) 4. Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) 5. Isolated Left Ventricular Non-Compaction Cardiomyopathy (LVNC). The Igenomix Cardiomyopathy Precision Panel serves as a diagnostic and tool ultimately leading to a better management and prognosis of the disease. It provides a comprehensive analysis of the genes involved in this disease using next-generation sequencing (NGS) to fully understand the spectrum of relevant genes. Indications The Igenomix Cardiomyopathy Precision Panel is indicated in those cases where there is a clinical suspicion of cardiomyopathy with or without the following manifestations: - Shortness of breath - Fatigue - Arrythmia (abnormal heart rhythm) - Family history of arrhythmia - Abnormal scans - Ventricular tachycardia - Ventricular fibrillation - Chest Pain - Dizziness - Sudden cardiac death in the family 1 Clinical Utility The clinical utility of this panel is: - The genetic and molecular diagnosis for an accurate clinical diagnosis of a patient with personal or family history of cardiomyopathy, channelopathy or sudden cardiac death. -
Hirschsprung Disease in an Infant with L1 Syndrome
Hirschsprung Disease in an Infant with L1 Syndrome: Report of a New Case and a Novel L1CAM Variant Teresa Andreone1 1Saint Louis University Care - The Physicians of Saint Louis University October 27, 2020 Abstract L1 syndrome is an X-linked disorder manifesting with congenital hydrocephalus, adducted thumbs and spasticity. There are rare cases of L1 syndrome and coincident Hirschsprung disease, with mutations in the L1CAM gene thought to underlie both. We present a novel pathogenic L1CAM variant in someone with L1 syndrome and Hirschsprung disease. Introduction The L1CAM gene encodes the membrane glycoprotein L1CAM, a calcium-independent cellular adhesion molecule involved in neuronal development. The L1CAM cell adhesion molecule is found on the X chromo- some in humans (and other mammals) and has a 1253 amino acid protein sequence. The extracellular portion is comprised of six immunoglobulin domains followed by five fibronectin type III domains which are con- nected to a small intracellular domain by a transmembrane helix (Figure 1). Mutations in theL1CAM gene cause L1 syndrome, which encompasses a spectrum of disease that includes four major X-linked conditions: X-linked congenital hydrocephalus due to stenosis of the aqueduct of Sylvius (HSAS; OMIM #307000); men- tal retardation, aphasia, shuffling gait and adducted thumbs syndrome (MASA; OMIM #303350); X-linked complicated hereditary spastic paraplegia type 1 (SPG1; OMIM#303350); and X-linked complicated agene- sis of the corpus callosum (OMIM #304100)1. More than 220 disease-causing variants in the L1CAM gene have been identified as causing the four major phenotypes of L1 syndrome2. Additionally, there are reports suggesting that additional mutations in L1CAM can cause mild behavioral and intellectual impairment3. -

WES Gene Package Multiple Congenital Anomalie.Xlsx
Whole Exome Sequencing Gene package Multiple congenital anomalie, version 5, 1‐2‐2018 Technical information DNA was enriched using Agilent SureSelect Clinical Research Exome V2 capture and paired‐end sequenced on the Illumina platform (outsourced). The aim is to obtain 8.1 Giga base pairs per exome with a mapped fraction of 0.99. The average coverage of the exome is ~50x. Duplicate reads are excluded. Data are demultiplexed with bcl2fastq Conversion Software from Illumina. Reads are mapped to the genome using the BWA‐MEM algorithm (reference: http://bio‐bwa.sourceforge.net/). Variant detection is performed by the Genome Analysis Toolkit HaplotypeCaller (reference: http://www.broadinstitute.org/gatk/). The detected variants are filtered and annotated with Cartagenia software and classified with Alamut Visual. It is not excluded that pathogenic mutations are being missed using this technology. At this moment, there is not enough information about the sensitivity of this technique with respect to the detection of deletions and duplications of more than 5 nucleotides and of somatic mosaic mutations (all types of sequence changes).

Prenatalscreen® Standard Technical Report
About PrenatalScreen® Prenatal Test PrenatalScreen® Prenatal Test is a genetic test that analyses fetal DNA, obtained from CVS or amniotic fluid following an invasive prenatal diagnosis, to screen for monogenic disorders in the fetus. Using the latest technologies, including Next Generation Sequencing (NGS), PrenatalScreen® Prenatal Test screen 744 genes for mutations causing over 1.000 severe genetic disorders in the fetus. PrenatalScreen® Prenatal Test allows for a comprehensive care and enables patients to make more informed reproductive decisions. Offering PrenatalScreen® Prenatal Test to a patient during pregnancy allows her to gain more knowledge about the potential to pass along a condition to the fetus. Aim of the test PrenatalScreen® Prenatal Test analyses DNA extracted from fetal cells in the amniotic fluid, collected through amniocentesis, or in the chorionic villi through villocentesis (CVS). The aim of this diagnositc test is to assess severe genetic diseases in the fetus, including the most common diseases in the European population. Genes listed in Table 1 were selected according to the incidence in the population of the disease caused by mutations in such genes, the severity of the clinical phenotype at birth and the importance of the related pathogenetic picture, in accordance with the indications of the American College of Medical Genetics (ACMG)(Grody et al., Genet Med 2013:15:482–483). PrenatalScreen®: Indication for testing PrenatalScreen® Prenatal Test is intended for patients who meet any of the following criteria: • Personal/familial anamnesis of hereditary genetic diseases; • For expectant mothers wishing to reduce the risk of a genetic diseases in the fetus; • For natural or in vitro fertilization (IVF)-derived pregnancies: • For couples using heterologus IVF procedures (egg/sperm donors). -
