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.9398C>G; p.Ser3133Cys variant (rs139089832) has not been reported in the medical literature, nor has it been previously identified by our laboratory. This variant has been reported to the ClinVar database as a variant of uncertain significance (Variation ID: 282459), and is listed in the Genome Aggregation Database (gnomAD) with an overall population frequency of 0.007 percent (identified on 20 out of 276,970 chromosomes). The serine at position 3133 is weakly conserved considering 12 species (Alamut v2.9.0) and computational analyses of the effects of the p.Ser3133Cys variant on protein structure and function provide conflicting results (SIFT: damaging, MutationTaster: polymorphism, PolyPhen-2: possibly damaging). Altogether, there is not enough evidence to classify the p.Ser3133Cys variant with certainty. -

Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is higher than would generally be expected for pathogenic variants in this gene. (http://gnomad.broadinstitute.org) Computational tools disagree on the variant's effect on normal protein function. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 3133 of the SYNE1 protein (p.Ser3133Cys). This variant is present in population databases (rs139089832, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with SYNE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 282459). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
