Genes affected

SYNE2 (HGNC:17084): (spectrin repeat containing nuclear envelope protein 2) The protein encoded by this gene is a nuclear outer membrane protein that binds cytoplasmic F-actin. This binding tethers the nucleus to the cytoskeleton and aids in the maintenance of the structural integrity of the nucleus. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is present in population databases (rs765407182, ExAC 0.006%). This sequence change replaces asparagine with serine at codon 2806 of the SYNE2 protein (p.Asn2806Ser). The asparagine residue is weakly conserved and there is a small physicochemical difference between asparagine and serine. This variant has not been reported in the literature in individuals with SYNE2-related disease. ClinVar contains an entry for this variant (Variation ID: 283216). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.8417A>G (p.N2806S) alteration is located in exon 48 (coding exon 47) of the SYNE2 gene. This alteration results from a A to G substitution at nucleotide position 8417, causing the asparagine (N) at amino acid position 2806 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
