AI Article Synopsis

  • DMDM (Domain mapping of disease mutations) is a database that maps disease mutations to specific gene, protein, or domain locations, providing a unique view of human coding mutations on protein domains.
  • It utilizes a sequence alignment tool (HMMer) to align human proteins with conserved protein domains, allowing for the identification and functional annotation of disease mutations and polymorphisms.
  • The database is accessible for free at http://bioinf.umbc.edu/dmdm and offers insights into molecular relationships among mutations from various diseases, surpassing traditional gene-centric visualization methods.

Article Abstract

Unlabelled: Domain mapping of disease mutations (DMDM) is a database in which each disease mutation can be displayed by its gene, protein or domain location. DMDM provides a unique domain-level view where all human coding mutations are mapped on the protein domain. To build DMDM, all human proteins were aligned to a database of conserved protein domains using a Hidden Markov Model-based sequence alignment tool (HMMer). The resulting protein-domain alignments were used to provide a domain location for all available human disease mutations and polymorphisms. The number of disease mutations and polymorphisms in each domain position are displayed alongside other relevant functional information (e.g. the binding and catalytic activity of the site and the conservation of that domain location). DMDM's protein domain view highlights molecular relationships among mutations from different diseases that might not be clearly observed with traditional gene-centric visualization tools.

Variations in the TP53 and KRAS genes indicate a particularly adverse prognosis in relapsed pediatric T-ALL. We hypothesized that these variations might be subclonally present at disease onset and contribute to relapse risk. To test this, we examined two cohorts of children diagnosed with T-ALL: one with 81 patients who relapsed and 79 matched non-relapsing controls, and another with 226 consecutive patients, 30 of whom relapsed.

Discovery of non-retinoid compounds that suppress the pathogenic effects of misfolded rhodopsin in a mouse model of retinitis pigmentosa.

PLoS Biol

January 2025

Department of Pharmacology and Cleveland Center for Membrane and Structural Biology, School of Medicine, Case Western Reserve University, Cleveland, Ohio, United States of America.

Pathogenic mutations that cause rhodopsin misfolding lead to a spectrum of currently untreatable blinding diseases collectively termed retinitis pigmentosa. Small molecules to correct rhodopsin misfolding are therefore urgently needed. In this study, we utilized virtual screening to search for drug-like molecules that bind to the orthosteric site of rod opsin and improve its folding and trafficking.

A novel COL3A1 gene variant associated with sudden death due to spontaneous pneumothorax.

Forensic Sci Med Pathol

January 2025

Department of Laboratory Medicine and Pathobiology, Faculty of Medicine, University of Toronto, Toronto, ON, Canada.

Spontaneous pneumothorax (SP) is a condition defined by abnormal gas accumulation in the chest cavity. Mutations of the collagen type III alpha 1 chain, COL3A1 gene, are primarily linked to vascular Ehlers-Danlos syndrome (vEDS); however, they can also contribute to structural changes in the tissue, like bullae of the lungs. In this case report, we present a young, thinly built boy who died due to a spontaneous pneumothorax.

Background: This study aimed to evaluate the efficacy of third-generation sequencing (TGS) and a thalassemia (Thal) gene diagnostic kit in identifying Thal gene mutations.

Methods: Blood samples (n = 119) with positive hematology screening results were tested using polymerase chain reaction (PCR)-based methods and TGS on the PacBio-Sequel-II-platform, respectively.

Results: Out of the 119 cases, 106 cases showed fully consistent results between the two methods, with TGS identified HBA1/2 and HBB gene mutations in 82 individuals.

Background: Familial hyperlipidemia (familial hypercholesterolemia, FH) is an autosomal genetic disorder. It includes type heterozygous familial hyperlipidemia (heterozygous familial hypercholesterolemia). HeFH is mainly caused by mutations in the LDLR, APOB, and PCSK9 genes and is characterized by elevated plasma low-density lipoprotein cholesterol levels.
