Complex encephalopathy associated to mutation in the GRIN2B gene: case report

نویسندگان

چکیده

Case presentation: 17-year-old female patient, single child of non-consanguineous healthy parents. The pregnancy and delivery were uneventful. She presented a normal psychomotor development until 4 months age, when she started with epileptic seizures evolved central hypotonia, appendicular hypertonia, dystonia. After, autistic features, stereotypies, lack response to pain, self-harm did not develop speech. refractory, different seizure types: absence, myoclonic, tonic, tonic-clonic gellastic seizures. In the first year life EEG revealed disorganization background activity predominating in left cerebral hemisphere multifocal epileptogenic activity. Video-EEG showed focal interictal discharges generalized projection predominance left, associated abnormal movements by patient. Complementary tests including karyotype, molecular study for Rett Syndrome, Angelman screening IEM. Serial MRI scans brain mild atrophy. Genetic NGS heterozygous mutation GRIN2B gene, which promotes substitution.

Hereditary Ataxia with a Novel Mutation in the Senataxin Gene: A Case Report

Hereditary ataxias (HA) are a group of inherited neurological disorders caused by changes in genes. At least 115 different mutations in the senataxin (SETX) gene causing ataxia have been identified. There are no reports of any SETX gene mutation among the Iranian population. Here we report on two cases with homozygous and heterozygous mutations in which one patient was affected by HA with oculo...

Atypical Omenn Syndrome Due to RAG2 Gene Mutation, a Case Report

Severe Combined Immunodeficiency (SCID), characterized by a profound decrease in both the number and function of T cells, is related to more than 20 different mutations. Recombination-activating gene (RAG) 1 and 2 seem to be two of the most common forms presenting with various manifestations, including typical SCID, Omenn syndrome (OS), atypical SCID (AS), or delayed onset combined immunodefici...

Myoclonic encephalopathy in the CDKL5 gene mutation.

OBJECTIVE Epilepsy with mutation of the CDKL5 gene causes early seizures and is a variant of Rett syndrome (MIM (312750), which is reported typically as infantile spasms. The purpose of this study was to analyze the epileptic histories and EEGs of patients with the CDKL5 mutation. METHODS We reviewed the epilepsy histories and electroclinical analyses of three girls aged 9.5, 7.4, and 9.4 yea...

Autosomal Recessive Nonsyndromic Hearing Loss: A Case Report with a Mutation in TRIOBP Gene

Hearing loss (HL) is the most common sensory defect. Various genetic as well as environmental factors have been shown to contribute in it. More than 100 loci have been recognized to cause autosomal recessive nonsyndromic hearing loss (ARNSHL). Here, we report a 6-year old female patient with bilateral pre-lingual HL in whom a mutation has been identified in TRIOBP gene (c.6362C>T, S2121L). In s...
