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	GeneDx	Apr 19, 2017	A variant of uncertain significance has been identified in the SYNE1 gene. The V5774M variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The V5774M variant is observed in 51/15508 (0.3%) alleles from individuals of South Asian background, (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The V5774M variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. However, this substitution occurs at a position that is conserved across species and in silico analysis predicts this variant is probably damaging to the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -

Feb 15, 2023

The SYNE1 c.17320G>A variant is predicted to result in the amino acid substitution p.Val5774Met. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.28% of alleles in individuals of South Asian descent in gnomAD, which may be too common to be a primary cause of disease (http://gnomad.broadinstitute.org/variant/6-152623012-C-T). 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. -
