SYNE1 encodes a spectrin repeat-containing protein that functions as a critical component of the LINC complex, which links the nuclear lamina to the cytoskeleton. This molecular bridge maintains subcellular spatial organization and transmits mechanical forces across the nuclear envelope, enabling nuclear movement and positioning. SYNE1 is particularly important during early ciliogenesis, where it mediates centrosome migration to the apical cell surface, and may coordinate nucleus-centrosome attachment through association with SUN1/2 and dynein-dynactin motor complexes. Mutations in SYNE1 cause Emery-Dreifuss muscular dystrophy type 4 (autosomal dominant), characterized by muscle weakness, early contractures, cardiac conduction abnormalities, and cardiomyopathy 1. SYNE1 was also identified as one of the most frequently mutated genes in autosomal recessive cerebellar ataxia, particularly in patients with spastic ataxia or early-onset disease 2. At the clinical level, SYNE1 mutations represent a treatable diagnostic target in neuromuscular disease evaluation, where genetic diagnosis guides management and cardiac monitoring strategies 1. Beyond neuromuscular disease, SYNE1 variants have been associated with female reproductive health conditions and identified as a recurrent driver in mantle cell lymphoma [PMID:40069456; 30], suggesting pleiotropic roles in development and neoplasia.
