Molecular delineation of small supernumerary marker chromosomes using a single nucleotide polymorphism array

Molecular Cytogenetics, 2020
Background Defining the phenotype-genotype correlation of small supernumerary marker chromosomes (sSMCs) remains a challenge in prenatal diagnosis. We karyotyped 20,481 amniotic fluid samples from pregnant women and explored the molecular characteristics

Seizures as the first manifestation of chromosome 2q24.2-q24.3 in a two and a half years old girl: A case report

Gynecology and Obstetrics Clinical Medicine, 2021
Background: Mutations and/or duplications in the chromosome 2q24.3 region are known to be responsible for various epilepsy phenotypes. However, microdeletion in childhood epilepsy is rarely reported. Case presentation: A two-and-a-half-year-old girl with

Prenatal sonographic findings in confirmed cases of Wolf-Hirschhorn syndrome

BMC Pregnancy and Childbirth, 2022
Background Wolf-Hirschhorn syndrome (WHS) is a common genetic condition and prenatal diagnosis is difficult due to heterogeneous expression of this syndrome and rather non-specific ultrasound findings.

Whole exome sequencing identified a novel compound heterozygous variation in COL7A1 gene causing dystrophic epidermolysis bullosa

Molecular Genetics & Genomic Medicine, 2022
Dystrophic epidermolysis bullosa (DEB) is a series of severe genetic conditions affecting skin and nails caused by mutations in the COL7A1 gene. DEB has a strong phenotypic variability.

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

Evaluation of the Efficacy and Safety of Satralizumab in a Pregnant NMOSD Patient With AQP4/MOG‐IgG Dual Seropositive: A Case Report

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Neuromyelitis Optica Spectrum Disorder (NMOSD) is a chronic autoimmune neuroinflammatory disease, typically characterized by antibodies against aquaporin 4 (AQP4‐IgG) or myelin oligodendrocyte glycoprotein (MOG‐IgG). Simultaneous seropositivity for both antibodies in a single patient is exceedingly rare.
