Genes affected
SYNE1 (HGNC:17089): (spectrin repeat containing nuclear envelope protein 1) This gene encodes a spectrin repeat containing protein expressed in skeletal and smooth muscle, and peripheral blood lymphocytes, that localizes to the nuclear membrane. Mutations in this gene have been associated with autosomal recessive spinocerebellar ataxia 8, also referred to as autosomal recessive cerebellar ataxia type 1 or recessive ataxia of Beauce. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

The c.12129_12137delAGAGCAAAC variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. This variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The c.12129_12137delAGAGCAAAC variant results in an in-frame deletion of 3 amino acids, denoted p.Glu4044_Thr4046del. However, other in-frame deletions have not been reported in the Human Gene Mutation Database in association with SYNE1-related disorders (Stenson et al., 2014). -
