We have identified a recurrent de novo pericentromeric deletion in 16p11.2-p12.2 in four individuals with developmental disabilities by microarray-based comparative genomic hybridization analysis. The identification of common clinical features in these four individuals along with the characterization of complex segmental duplications flanking the deletion regions suggests that nonallelic homologous recombination mediated these rearrangements and that deletions in 16p11.2-p12.2 constitute a previously undescribed syndrome.

The recent discovery of nonvisual photoreceptors in various organs has raised expectations for uncovering their roles and underlying mechanisms. In this work, we identified a previously unrecognized hormone-releasing mechanism in the pituitary of the Japanese rice fish (medaka) induced by light. Ca imaging analysis revealed that melanotrophs, a type of pituitary endocrine cell that secretes melanocyte-stimulating hormone, robustly increase the concentration of intracellular Ca during short-wavelength light exposure.

Inter-coronary communication is a rare congenital anomaly, defined as a connection between two patent coronary arteries, and was first described in 1972. We report the case of a 61-year-old Emirati female who presented to the emergency department with chest pain and palpitations, along with a strong family history of cardiac disease. She was initially diagnosed with indolent hypertrophic obstructive cardiomyopathy and accordingly managed; however, the patient remained symptomatic.

Recent advances in immunology have challenged the conventional division of T-lymphocyte function by uncovering novel subpopulations with diverse roles and characteristics. This article reviews these discoveries and their implications for understanding immune regulation and disease pathogenesis. Innovative techniques have enabled the identification of previously unrecognized T-lymphocyte subsets, disrupting the classical classification system.

The IncRNA was initially believed to be dispensable for physiology due to the lack of observable phenotypes in knockout (KO) mice. However, our study challenges this conclusion. We found that both KO and conditional KO mice in the osteoblast lineage exhibit significant osteoporosis.

Genome-wide collections of yeast strains, known as libraries, revolutionized the way systematic studies are carried out. Specifically, libraries that involve a cellular perturbation, such as the deletion collection, have facilitated key biological discoveries. However, short-term rewiring and long-term accumulation of suppressor mutations often obscure the functional consequences of such perturbations.
