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]

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 predict that this variant is not damaging. -

The c.14288G>A (p.R4763Q) alteration is located in exon 77 (coding exon 76) of the SYNE1 gene. This alteration results from a G to A substitution at nucleotide position 14288, causing the arginine (R) at amino acid position 4763 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 4763 of the SYNE1 protein (p.Arg4763Gln). This variant is present in population databases (rs141883764, gnomAD 0.09%). 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: 286148). 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 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.14288G>A variant is predicted to result in the amino acid substitution p.Arg4763Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.084% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/6-152651319-C-T), which is more common than expected for a disease-causing variant. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
