Species with U‐shaped geographic ranges as an opportunity to study early stages of divergence: The case of Ipomoea microsepala

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The study of the early stages of divergence between populations is crucial to understanding how species and biodiversity originate. Geographic distributions that capture some aspects of the process of divergence, such as those that are markedly U‐shaped, could offer a window to identify systems undergoing incipient speciation, which ...

Candidate Single Nucleotide Polymorphism Markers for Arsenic Responsiveness of Protein Targets

open access: yesBioinformatics and Biology Insights, 2010
Arsenic is a toxic metalloid that causes skin cancer and binds to cysteine residues—a property that could be used to infer arsenic responsiveness of a target protein.

Evolutionary history and taxonomy of the genus Zea

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Taxonomic differentiation of teosinte species (Zea spp.), the closest relatives of maize (Z. mays) is crucial for understanding their distribution, ecology, and evolutionary history. Resolving the taxonomic uncertainties is of scientific interest and has practical implications for biodiversity management, preservation, and utilization.

Severe Phenotype in an Indian Family With Progressive Pseudorheumatoid Arthropathy of Childhood

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Progressive pseudorheumatoid arthropathy of childhood (PPAC) is a rare autosomal recessive progressive condition that affects the cartilage of joints and bones. The symptoms of PPAC include stiffness of the joints, bony swelling of the toes and fingers, short stature, kyphosis, and muscle weakness.

Concurrent Germline RB1 & Mosaic TP53 in a Child With Multiple Childhood Cancers

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We report a patient with a pathogenic germline variant (PGV) in RB1 and somatic mosaicism for a pathogenic TP53 variant who developed three distinct types of childhood cancer: retinoblastoma, osteosarcoma, and myelodysplastic syndrome (MDS) before the age of 6 years.

Heterozygous Variants in LRP1 Cause a Neurodevelopmental Disorder With Congenital Heart Defects

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT LRP1 encodes the low‐density lipoprotein (LDL) receptor‐related protein 1 (LRP1), a transmembrane protein involved in endocytosis and activation of multiple signaling pathways. LRP1 variants have been implicated in the pathogenesis of congenital heart defects (CHD), Alzheimer's disease, and neurodevelopmental disorders (NDD).

Time‐Resolved Multidimensional NMR Spectroscopy Reveals the Bifurcated Folding Pathway of a Thrombin‐Binding DNA G4–Azobenzene Derivative Complex

open access: yesAngewandte Chemie, EarlyView.
A photoswitchable ligand was used to trigger conformational changes within the thrombin binding aptamer DNA G‐Quadruplex. These reversible ligand driven rearrangements were examined by time‐resolved NMR experiments to gain insight of the dynamic folding landscape of the G‐quadruplex.
