Adhesion of leukocytes to endothelial cells via cell adhesion molecules (CAMS) is thought to be pivotal in the initiation of atherosclerosis. As patients with familial hypercholesterolaemia (FH) are known to develop severe, premature coronary artery disease (CAD), we investigated the usefulness of soluble forms of CAMS namely vascular cellular adhesion molecule-1 (VCAM), intercellular cell adhesion molecule-1 (ICAM) and E-selectin as predictive markers of the presence and severity of atherosclerosis in this patient group. Twenty heterozygous FH patients without CAD; 24 heterozygous FH patients with CAD; 17 homozygous FH patients without documented CAD; nine homozygous FH patients with overt CAD; and 50 healthy controls were studied. Carotid artery intima media thickness (IMT) was also measured in the homozygous patients. Levels of the adhesion molecules VCAM, ICAM and E-selectin were not significantly elevated in homozygous FH patients and heterozygous FH patients, both with and without CAD, compared to the normal control subjects. In addition the range of results was so wide and the overlap of values with normal controls so great, that the use of an individual level of either VCAM, ICAM or E-selectin was not predictive of either the presence or degree of atherosclerosis in the FH subjects.

Objectives: Acetylated tubulin is a hallmark of flagellar stability in spermatozoa, and studies have demonstrated the ability of CDYL to function as a tubulin acetyltransferase in spermatozoa. Of note, germline conditional knockout of Cdyl can lead to asthenoteratozoospermia and infertility in male mice. However, the role of CDYL gene in human fertility remains uncharacterized.

Background: This study aimed to develop and validate a targeted next-generation sequencing (NGS) panel along with a data analysis algorithm capable of detecting single-nucleotide variants (SNVs) and copy number variations (CNVs) within the beta-globin gene cluster. The aim was to reduce the turnaround time in conventional genotyping methods and provide a rapid and comprehensive solution for prenatal diagnosis, carrier screening, and genotyping of β-thalassemia patients.
Methods And Results: We devised a targeted NGS panel spanning an 80.

Background: Li-Fraumeni syndrome (LFS) is an autosomal dominant tumor predisposition syndrome characterized by a high familial incidence of various malignancies. It results from pathogenic/likely pathogenic heterozygous constitutional variants of the TP53 gene. Due to impaired DNA damage repair, conventional cytotoxic therapies or radiotherapy should be avoided whenever feasible to mitigate the high incidence of treatment-related secondary malignancies in these patients.

Aims: Sarcoendoplasmic reticulum Ca-ATPase 2 (SERCA2), encoded by ATP2A2, is a key protein involved in intracellular Ca homeostasis. The SERCA2a isoform is predominantly expressed in cardiomyocytes and type I myofibres. Variants in this gene are related to Darier disease, an autosomal dominant dermatologic disorder, but have never been linked to myopathy.

Mutations or homozygous deletions of MHC class II (MHC-II) genes are commonly found in B cell lymphomas that develop in immune-privileged sites and have been associated with patient survival. However, the mechanisms regulating MHC-II expression, particularly through genetic and epigenetic factors, are not yet fully understood. In this study, we identified a key signaling pathway involving the histone H2AK119 deubiquitinase BRCA1 associated protein 1 (BAP1), the interferon regulatory factor interferon regulatory factor 1 (IRF1), and the MHC-II transactivator class II transactivator (CIITA), which directly activates MHC-II gene expression.
