Identification of Unexpected Pathomechanisms Underlying the Human Usher Syndrome.

Human Usher syndrome (USH) is the most common form of hereditary deaf-blindness, characterized by inner ear defects and late-onset vision loss. USH is a complex genetic disorder, clinically and genetically heterogeneous. To date, there is no treatment for the ocular phenotype of any USH subtype, as the underlying pathomechanisms of the disease in the eye are far from being understood.

The Usher syndrome 1C protein harmonin regulates canonical Wnt signaling.

Human Usher syndrome (USH) is the most common form of hereditary combined deaf-blindness. USH is a complex genetic disorder, and the pathomechanisms underlying the disease are far from being understood, especially in the eye and retina. The gene encodes the scaffold protein harmonin which organizes protein networks due to binary interactions with other proteins, such as all USH proteins.

Primary cilia and SHH signaling impairments in human and mouse models of Parkinson's disease.

Parkinson's disease (PD) as a progressive neurodegenerative disorder arises from multiple genetic and environmental factors. However, underlying pathological mechanisms remain poorly understood. Using multiplexed single-cell transcriptomics, we analyze human neural precursor cells (hNPCs) from sporadic PD (sPD) patients.
