WebAug 20, 2024 · Lamin, an intermediate filament protein of the nuclear lamina, confers structural strength to the nuclear membrane. 1 Mutations in LMNA (OMIM code 150330), the gene encoding lamins A and C, have been known to cause a wide spectrum of disorders known as laminopathies. WebTo test this, we performed genome-wide chromosome conformation analyses in human induced pluripotent stem cell–derived cardiomyocytes (hiPSC-CMs) with a haploinsufficient mutation for lamin A/C. Compared with gene-corrected cells, mutant hiPSC-CMs have marked electrophysiological and contractile alterations, with modest gene expression …
WebMutations in the LMNA gene cause a collection of diseases known as laminopathies, including muscular dystrophies, lipodystrophies, and early-onset aging syndromes. The LMNA gene encodes A-type lamins, lamins A/C, intermediate filaments that form a meshwork underlying the inner nuclear membrane. Lamins have a conserved domain … WebMar 16, 2024 · Mutations in the nuclear structural protein lamin A produce rare, tissue-specific diseases called laminopathies.
