Genetic dyslipidemias.

Annales d'endocrinologie2026 Mar 20

Although genetic factors strongly influence lipid metabolism, genetic dyslipidemias refer to specific monogenic defects that significantly alter the function of proteins involved in lipid metabolism. Familial hypercholesterolemia results from mutations in the genes coding for LDL receptor, apolipoprotein B100 (apoB100), PCSK9, or LDLRAP1. The rare homozygous form is severe, with extravascular lipid deposits at an early age and a high incidence of coronary events in childhood, in the absence of early diagnosis. The heterozygous form is more frequent and characterized by elevated plasma LDL cholesterol levels (>190 mg/dL in adults) and a very high risk of premature coronary artery disease (usually before the age of 50 years). Familial chylomicronemia syndrome (FCS) is a major form of genetic hypertriglyceridemia caused by mutations in genes encoding lipoprotein lipase or one of its cofactors (apoC-II, apoA-V, GPIHBP1, or LMF1). Patients with FCS exhibit markedly elevated plasma triglyceride levels (>10 mmol/L) and are at high risk for acute pancreatitis. Congenital familial partial lipodystrophy and glycogen storage diseases are two other forms of genetic hypertriglyceridemia. In addition, other rare genetic dyslipidemias have been described in humans, including familial dysbetalipoproteinemia, abetalipoproteinemia, familial hypobetalipoproteinemia, familial combined hypolipidemia, sitosterolemia, and hypoalphalipoproteinemias.

The Role of Visual Electrophysiology in Systemic Hereditary Syndromes.

International journal of molecular sciences2025 Jan 23

Visual electrophysiology is a valuable tool for evaluating the visual system in various systemic syndromes. This review highlights its clinical application in a selection of syndromes associated with hearing loss, mitochondrial dysfunction, obesity, and other multisystem disorders. Techniques such as full-field electroretinography (ffERG), multifocal electroretinography (mfERG), pattern electroretinography (PERG), visual evoked potentials (VEP), and electrooculography (EOG) offer insights into retinal and optic nerve function, often detecting abnormalities before clinical symptoms manifest. In hearing loss syndromes like Refsum disease, Usher syndrome (USH), and Wolfram syndrome (WS), electrophysiology facilitates the detection of early retinal changes that precede the onset of visual symptoms. For mitochondrial disorders such as maternally-inherited diabetes and deafness (MIDD), Kearns-Sayre syndrome (KSS), and neuropathy, ataxia, and retinitis pigmentosa (NARP) syndrome, these tests can be useful in characterizing retinal degeneration and optic neuropathy. In obesity syndromes, including Bardet-Biedl syndrome (BBS), Alström syndrome, and Cohen syndrome, progressive retinal degeneration is a hallmark feature. Electrophysiological techniques aid in pinpointing retinal dysfunction and tracking disease progression. Other syndromes, such as Alagille syndrome (AGS), abetalipoproteinemia (ABL), Cockayne syndrome (CS), Joubert syndrome (JS), mucopolysaccharidosis (MPS), Neuronal ceroid lipofuscinoses (NCLs), and Senior-Løken syndrome (SLS), exhibit significant ocular involvement that can be evaluated using these methods. This review underscores the role of visual electrophysiology in diagnosing and monitoring visual system abnormalities across a range of syndromes, potentially offering valuable insights for early diagnosis, monitoring of progression, and management.

Thirty-Three Years Follow-Up of a Greek Family with Abetalipoproteinemia: Absence of Liver Damage on Long-Term Medium Chain Triglycerides Supplementation.

Journal of personalized medicine2025 Aug 04

Background: The long-term clinical and laboratory results of a 33-year follow-up of a Greek family with abetalipoproteinemia (ABL) are described. Case Report: The patients (two brothers and their sister, aged 57, 49, and 62 years, respectively) are still alive, being under close surveillance. In two of the three patients, diarrhea appeared in early infancy, while in the third, it appeared during adolescence. CNS symptomatology worsened after the second decade of life. At the same time, night blindness appeared in the advanced stages of the disease, resulting in almost complete loss of vision in one of the male patients and severe impairment in the other. The diagnosis was based on the clinical picture, ophthalmological findings, serum lipid estimations, and presence of peripheral acanthocytosis. All patients exhibited typical serum lipidemic profile, ophthalmological findings, and acanthocytes in the peripheral blood. During the follow-up period, strict dietary modifications were applied, including the substitution of fat with medium-chain triglycerides (MCT oil). After 33 years since the initial diagnosis, all patients are alive without any sign of liver dysfunction despite continuous use of MCT oil. However, symptoms from the central nervous system and vision impairment worsened. Conclusion: The course of these patients suggests that the application of a modified diet, including MCT oil, along with close surveillance, could prolong the survival of patients without significant side effects from the liver.

Delayed Tricep Repair Using Dermal Allograft: Technique and Case Examples.

Techniques in hand &amp; upper extremity surgery2025 Sep 01

An acellular dermal matrix is a biological graft composed of several components present in the dermis such as collagen fibers, elastin, fibronectin, and hyaluronic acid that serve as support for cellular repopulation that will gradually become vascularized. This provides mechanical resistance and improves suture retention. With this article we aim to present 2 cases, and our technique, in which a rupture of the distal triceps tendon occurred, patients presented late due to usual insurance authorization delays, and then required delayed surgical repair by means of dermal acellular matrix grafting in order to bridge the substantial gap due to tricep proximal retraction. The first case report describes a 55-year-old male with abetalipoproteinemia who suffered an unclear injury to his right triceps tendon and apparently an olecranon bursitis and/or tricep tendonitis. Surgical intervention involved exploring the triceps tendon, revealing degenerative tissue and a detached muscle belly that was unrepairable, necessitating immediate reconstruction with a dermal allograft. The poor quality of the triceps tendon, weakened by cortisone injections, precluded primary repair, highlighting the rationale for graft reconstruction. The second case concerns a 54-year-old male, a gym owner and amateur bodybuilder, who suffered a fracture of the lateral epicondyle with avulsion of the distal triceps following a motorcycle accident. The patient underwent surgery with end-to-end suturing of the tendon and augmentation of the suture using acellular dermal matrix. The successful use of a dermal allograft in surgical reconstruction presents a promising solution in cases with insufficient tendon quality.

Binding of Selected Ligands to Human Protein Disulfide Isomerase and Microsomal Triglyceride Transfer Protein Complex and the Associated Conformational Changes: A Computational Molecular Modelling Study.

ChemistryOpen2025 Apr

Human protein disulfide isomerase (PDI) is a multifunctional protein, and also serves as the β subunit of the human microsomal triglyceride transfer protein (MTP) complex, a lipid transfer machinery. Dysfunction of the MTP complex is associated with certain disease conditions such as abetalipoproteinemia and cardiovascular diseases. It is known that the functions of PDI or the MTP complex can be regulated by the binding of a small-molecule ligand to either of these two proteins. In the present study, the conformational changes of the MTP complex upon the binding of three selected small-molecule ligands (17β-estradiol, lomitapide and a phospholipid) are investigated based on the available biochemical and structural information by using the protein-ligand docking method and molecular dynamics (MD) simulation. The ligand-binding sites, the binding poses and binding strengths, the key binding site residues, and the ligand binding-induced conformational changes in the MTP complex are analyzed based on the MD trajectories. The open-to-closed or closed-to-open transitions of PDI is found to occur in both reduced and oxidized states of PDI and also independent of the presence or absence of small-molecule ligands. It is predicted that lomitapide and 1,2-diacyl-sn-glycero-3-phosphocholine (a phospholipid) can bind inside the lipid-binding pocket in the MTP complex with high affinities, whereas 17β-estradiol interacts with the lipid-binding pocket in addition to its binding to the interface region of the MTP complex. Additionally, lomitapide can bind to the b' domain of PDI as reported earlier for E2. Key residues for the ligand-binding interactions are identified in this study. It will be of interest to further explore whether the binding of small molecules can facilitate the conformational transitions of PDI in the future. The molecular and structural insights gained from the present work are of value for understanding some of the important biological functions of PDI and the MTP complex.
