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]

Collection Method:clinical testing

The p.His8170Gln variant (rs141586001) has not been reported in the medical literature, gene specific variation databases, nor has it been previously identified by our laboratory. This variant is listed in the Genome Aggregation Database (gnomAD) with a population frequency of 0.1 percent in the European Non-Finnish population (identified on 145 out of 125,962 chromosomes), and has been reported to the ClinVar database with conflicting interpretations. The histidine at position 8170 is weakly conserved and computational analyses of the p.His8170Gln variant on protein structure and function indicate a neutral effect (SIFT: tolerated, MutationTaster: polymorphism, PolyPhen-2: benign). Altogether, there is not enough evidence to classify the p.His8170Gln variant with certainty. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 8170 of the SYNE1 protein (p.His8170Gln). This variant is present in population databases (rs141586001, gnomAD 0.1%), and has an allele count higher than expected for a pathogenic variant. 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: 194306). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The glutamine 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. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The SYNE1 c.24510C>G variant is predicted to result in the amino acid substitution p.His8170Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.12% of alleles in individuals of European (Non-Finnish) descent in gnomAD, including one homozygous individual (http://gnomad.broadinstitute.org/variant/6-152469433-G-C). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Significance:Likely benign
Review Status:criteria provided, single submitter

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
