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]

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 3602 of the SYNE1 protein (p.Asn3602Ser). This variant is present in population databases (rs148212715, gnomAD 0.03%). This missense change has been observed in individual(s) with cerebellar ataxia, congenital cerebellar hypoplasia, and cognitive impairment (PMID: 30275942). ClinVar contains an entry for this variant (Variation ID: 285321). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
