Moderate the MAOA-L Allele Expression with CRISPR/Cas9 System
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 23 April 2018 doi:10.20944/preprints201804.0275.v1 1 Review 2 Moderate the MAOA-L Allele Expression with CRISPR/Cas9 System 3 Martin L. Nelwan 4 Department of Animal Science – Other 5 Nelwan Institution for Human Resource Development 6 Jl. A. Yani No. 24 7 Palu, Sulawesi Tengah, Indonesia 8 Email: [email protected] 9 Abstract: Antisocial behavior is a behavior disorder inherited according to the inheritance of X-linked 10 chromosome. Mutations in the MAOA gene can cause different behaviors in humans. These can comprise 11 violent behavior or antisocial behavior. Low MAOA (MAOA-L) allele activity can cause antisocial 12 behavior in both healthy and unhealthy people. Antisocial from healthy males can originate from 13 maltreatment during childhood. There are no drugs for the treatment of antisocial behavior permanently 14 at this time. MAOA inhibitor can reverse antisocial behavior in animal models. To cure antisocial 15 behavior in the future, the CRISPR/Cas9 system in combination with iPSCs or ssODN methods for 16 instance can be used. This system has succeeded to correct erroneous segments in the F8 gene and F9 17 gene. Both genes occupy the X chromosome. The MAOA gene also occupies the X chromosome. It seems 18 that CRISPR/Cas9 system may be a beneficial tool to edit erroneous segments in the MAOA gene to treat 19 antisocial behavior. 20 Keywords: advanced therapy, aggressive, antisocial, behavior, MAOA. 21 22 1. Introduction 23 Antisocial behavior is a hereditary disorder inherited through an X-linked recessive inheritance 24 pattern. -
MR Imaging of Kallmann Syndrome, a Genetic Disorder of Neuronal Migration Affecting the Olfactory and Genital Systems
MR Imaging of Kallmann Syndrome, a Genetic Disorder of Neuronal Migration Affecting the Olfactory and Genital Systems 1 2 2 3 4 Charles L. Truwit, ' A. James Barkovich, Melvin M. Grumbach, and John J. Martini PURPOSE: We report the MR findings in nine patients with clinical and laboratory evidence of Kallmann syndrome (KS), a genetic disorder of olfactory and gonadal development. In patients with KS, cells that normally express luteinizing hormone-releasing hormone fail to migrate from the medial olfactory placode along the terminalis nerves into the forebrain. In addition, failed neuronal migration from the lateral olfactory placode along the olfactory fila to the forebrain results in aplasia or hypoplasia of the olfactory bulbs and tracts. Patients with KS, therefore, suffer both reproductive and olfactory dysfunction. METHODS: Nine patients with KS underwent direct coronal MR of their olfactory regions in order to assess the olfactory sulci, bulbs, and tracts. A lOth patient had MR findings of KS, although the diagnosis is not yet confirmed by laboratory tests. RESULTS: Abnormalities of the olfactory system were identified in all patients. In particular, the anterior portions of the olfactory sulci were uniformly hypoplastic. The olfactory bulbs and tracts appeared hypoplastic or aplastic in all patients in whom the bulb/ tract region was satisfactorily imaged. In two (possibly three) patients, prominent soft tissue in the region of the bulbs suggests radiographic evidence of neurons that have been arrested before migration. CONCLUSIONS: Previous investigators of patients with KS used axial MR images to demonstrate hypoplasia of the olfactory sulci but offered no assessment of the olfactory bulbs. -

Procedures addressed The inclusion of any procedure code in this table does not imply that the code is under management or requires prior authorization. Refer to the specific Health Plan's procedure code list for management requirements. Procedures addressed by this Procedure codes guideline IBMFS Multigene panel 81479 What are inherited bone marrow failure syndromes Definition Bone marrow failure (BMF) is the inability of the bone marrow to produce a sufficient quantity of functional blood cells to meet physiologic demands.1 BMF is typically classified into three categories, based on presumed etiology: inherited, secondary, or idiopathic.1 Inherited bone marrow failure syndromes (IBMFSs) are a group of genetically defined disorders that are characterized by BMF. Individuals presenting with aplastic anemia (AA), myelodysplastic syndrome (MDS), acute myeloid leukemia (AML), and chronic unexplained cytopenias should be evaluated for an IBMFS.1 Incidence "The incidence of inherited bone marrow failures accounts for 10% to 15% of marrow aplasia and 30% of pediatric bone marrow failure disorders with approximately 65 cases per million live births every year."2 Seventy-five percent of children with an IBMFS have an identifiable cause.2 ©2021 eviCore healthcare.

Summary Clinical characteristics. McLeod neuroacanthocytosis syndrome (designated as MLS throughout this review) is a multisystem disorder with central nervous system (CNS), neuromuscular, and hematologic manifestations in males. CNS manifestations are a neurodegenerative basal ganglia disease including (1) movement disorders, (2) cognitive alterations, and (3) psychiatric symptoms. Neuromuscular manifestations include a (mostly subclinical) sensorimotor axonopathy and muscle weakness or atrophy of different degrees. Hematologically, MLS is defined as a specific blood group phenotype (named after the first proband, Hugh McLeod) that results from absent expression of the Kx erythrocyte antigen and weakened expression of Kell blood group antigens. The hematologic manifestations are red blood cell acanthocytosis and compensated hemolysis. Allo-antibodies in the Kell and Kx blood group system can cause strong reactions to transfusions of incompatible blood and severe anemia in newborns of Kell-negative mothers. -

CHARGE association denotes the non-random occurrence of ocular coloboma, heart defects, choanal atresia, retarded growth and development, genital hypoplasia, ear anomalies and deafness (OMIM #214800). Almost all patients with CHARGE association are sporadic and its cause was unknown. We and others hypothesized that CHARGE association is due to a genomic microdeletion or to a mutation in a gene affecting early embryonic development. In this study array- based comparative genomic hybridization (array CGH) was used to screen patients with CHARGE association for submicroscopic DNA copy number alterations. De novo overlapping microdeletions in 8q12 were identified in two patients on a genome-wide 1 Mb resolution BAC array. A 2.3 Mb region of deletion overlap was defined using a tiling resolution chromosome 8 microarray. Sequence analysis of genes residing within this critical region revealed mutations in the CHD7 gene in 10 of the 17 CHARGE patients without microdeletions, including 7 heterozygous stop-codon mutations. -

This review aims to provide a clinical approach to the diagnosis of this complex group of patients by addressing key questions including the predominant neurological syndrome associated with the neuropathy e.g. spasticity, the type of neuropathy, and the other neurological and non- neurological features of the syndrome. Priority is given to the diagnosis of treatable conditions. Using this approach, we associated neuropathy with one of three major syndromic categories - 1) ataxia, 2) spasticity, and 3) global neurodevelopmental impairment. Syndromes that do not fall easily into one of these three categories can be grouped according to the predominant system involved in addition to the neuropathy e.g. -

Tr io Health Meet OMS Warrior ALEXA What is OMS? OPSOCLONUS-MYOCLONUS SYNDROME General Discussion Opsoclonus-myoclonus syndrome (OMS) is an inflammatory neurological disorder, often occurring as a paraneoplastic syndrome with neurological symptoms being the first sign of an occult tumor. It is characterized by associated ocular, motor, behavioral, sleep, and language disturbances. The onset is oftentimes abrupt and can be relatively severe, with the potential to become chronic unless the appropriate diagnosis and treatment are reached in a timely manner. Signs and Symptoms The component features of OMS include the presence of rapid, seemingly random eye movements in the horizontal, vertical, and diagonal directions (opsoclonus); an unsteady gait or inability to walk or stand (ataxia); and brief, repetitive, shock-like muscle spasms or tremors within the arms, legs, or hands interfering with normal use (myoclonus). Behavioral and sleep disturbances, including extreme irritability, inconsolable crying, reduced or fragmented sleep (insomnia), and rage attacks are common. Difficulty articulating speech (dysarthria), sometimes with complete loss of speech and language, may occur. Additional symptoms, such as decreased muscle tone (hypotonia) and vomiting, have also been noted. Causes The most common cause of OMS in young children is an occult (ie, a small, often hidden) tumor. The symptoms of OMS, as a paraneoplastic syndrome, presumably stem from the immune system attacking the tumor, leading to secondary inflammatory effects on the central nervous system. -
