Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

Advanced Science, EarlyView.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

A Novel Missense Variant in LMX1A Leads to Autosomal Dominant Nonsyndromic Hearing Loss

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Hereditary nonsyndromic hearing loss (NSHL) is a prevalent entity associated with over 150 known causative genes, including LMX1A, which has fewer than 10 reported pathogenic variants. Here we present a novel missense variant in LMX1A in a family of European descent with hereditary hearing loss. Clinical and family histories were obtained, and

Clinical Presentation of the Longest Reported Living Individual With Bent Bone Dysplasia—FGFR2‐Related

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The FGFR2 gene, encoding the FGFR2 protein, plays a crucial role in embryonic cell development, particularly in bone tissue. Bent Bone Dysplasia (BBD), FGFR2‐related (MIM# 614592), is a rare severe skeletal dysplasia characterized by craniofacial differences, reduced bone mineral density, and bowed long bones.
