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]

Uncertain significance, criteria provided, single submitter	clinical testing	Revvity Omics, Revvity	Feb 09, 2021	- -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jan 25, 2017	The R3038G variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The R3038G variant is observed in 10/10354 (0.1%) alleles from individuals of African background (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This substitution occurs at a position where amino acids with similar properties to Arginine are tolerated across species. However, this variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Additionally, in silico analysis predicts this variant is probably damaging to the protein structure/function. -

This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 3038 of the SYNE1 protein (p.Arg3038Gly). This variant is present in population databases (rs144643941, gnomAD 0.1%). 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: 393008). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glycine 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. -
