Prenatal diagnosis of chromothripsis causing complex chromosomal rearrangement involving chromosomes 5, 7 and 11 leading to TWIST1 deletion and Saethre-Chotzen syndrome.

Objective: Prenatal detection of complex chromosomal rearrangements (CCR) is extremely rare, but is of great clinical importance, since CCR can be causative of different congenital disorders. We present an exceptionally rare case of prenatally diagnosed Saethre-Chotzen syndrome (SCS) rising as a consequence of chromothripsis involving chromosomes 5, 7 and 11 and deletion of TWIST1 gene.

Case Report: Brachycephaly, hypertelorism, flat face, micrognathia, relative macroglossia and small posterior fossa were noted on ultrasound examination at 28th gestational week.

B7 homolog 3 in pancreatic cancer.

Despite advances in cancer treatment, pancreatic cancer (PC) remains a disease with high mortality rates and poor survival outcomes. The B7 homolog 3 (B7-H3) checkpoint molecule is overexpressed among many malignant tumors, including PC, with low or absent expression in healthy tissues. By modulating various immunological and nonimmunological molecular mechanisms, B7-H3 may influence the progression of PC.

Association of rs1800795, but not rs1800629, and rs16944 polymorphisms' genotypes with recovery of ischemic stroke patients following thrombolysis.

Objectives: Inflammatory cytokines like tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-6 can cause brain injury, slow recovery, and adverse effects (ADEs) in ischemic stroke (IS) patients treated with recombinant tissue plasminogen activator (rtPA). We explored the relationship between selected polymorphisms within , and genes, and post-IS outcome and ADEs in patients treated with rtPA.

Methods: One hundred and sixty-six patients with IS treated with rtPA were included in this study.

Chromosomal microarray in postnatal diagnosis of congenital anomalies and neurodevelopmental disorders in Serbian patients.

Background: Array-based genomic analysis is a gold standard for the detection of copy number variations (CNVs) as an important source of benign as well as pathogenic variations in humans. The introduction of chromosomal microarray (CMA) has led to a significant leap in diagnostics of genetically caused congenital malformations and neurodevelopmental disorders, with an average diagnostic yield of 15%. Here, we present our experience from a single laboratory perspective in four years' postnatal clinical CMA application.

Parental Stress of Children with Autism Spectrum Disorder During the Coronavirus Pandemic (COVID-19): Experience from Serbia.

Objective: Taking care of children with autism spectrum disorder (ASD), as of children with other developmental disorders, is associated with greater parental stress. The aim of this study was to determine the prevalence and impact of integrative and co-morbid ASD-related symptoms on parental stress levels during the COVID-19 pandemic at four time points. Testing was performed during significant changes related to the state of the COVID-19 pandemic in Serbia.

Premutations in the FMR1 gene in Serbian patients with undetermined tremor, ataxia and parkinsonism.

: Although one of the most common monogenic late-onset neurodegenerative disorders, fragile-X-associated tremor/ataxia syndrome (FXTAS) is still underdiagnosed. The aim of the present study was to estimate the frequency of premutation carriers in patients with unexplained degenerative ataxias, action tremor or parkinsonism, and action tremor with or without associated cognitive impairment.: The study comprised 100 consecutive patients with the disease onset >49 years who had any form of unexplained action tremor, cerebellar ataxia, followed by parkinsonism with or without incipient dementia, and in whom the repeats size was determined.

Analysis of the Association Between Polymorphisms within PAI-1 and ACE genes and Ischemic Stroke Outcome After rt-PA Therapy.

Purpose: Treatment of Ischemic stroke (IS) in acute phase is based on the use of thrombolytic rt-PA therapy. We aimed to determine whether different alleles and genotypes of I/D ACE gene and 4G/5G PAI-1 gene polymorphisms may influence outcome of rt-PA therapy in patients with IS and the occurrence of haemorrhagic transformation (HT).

Methods: Our study included 94 consecutive patients with IS treated with rt-PA.

Evaluation of cytokine genetic polymorphisms in adult patients with common variable immunodeficiency: A single-center study.

Common variable immunodeficiency (CVID) is a heterogeneous disease characterized by impaired B-cell differentiation and maturation accompanied with the defective antibody production. Several investigators addressed the possibility that disturbed cytokine production of TNF, IL-6, IFN-γ and IL-10, among a variety of others, may be implicated in CVID. The aim of this study was to test the hypothesis that genetic polymorphisms involving TNF (-308G/A), IFNG (+874 T/A), IL10 (-1082G/A, -819T/C and -592A/C), and IL6 (-174G/C) cytokine genes might contribute to susceptibility to CVID.
