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

The c.10928G>A (p.R3643Q) alteration is located in exon 54 (coding exon 53) of the SYNE2 gene. This alteration results from a G to A substitution at nucleotide position 10928, causing the arginine (R) at amino acid position 3643 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Sep 11, 2023
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant has not been reported in the literature in individuals affected with SYNE2-related conditions. This variant is present in population databases (rs748433814, gnomAD 0.01%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 3643 of the SYNE2 protein (p.Arg3643Gln). ClinVar contains an entry for this variant (Variation ID: 565502). 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. -
