Variant summary
Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBS1_SupportingBS2
The NM_182914.3(SYNE2):c.20524G>A(p.Gly6842Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000273 in 1,613,946 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G6842R) has been classified as Likely benign.

Submissions by phenotype
not specified Uncertain:1
The c.20524G>A (p.G6842S) alteration is located in exon 116 (coding exon 115) of the SYNE2 gene. This alteration results from a G to A substitution at nucleotide position 20524, causing the glycine (G) at amino acid position 6842 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Emery-Dreifuss muscular dystrophy 5, autosomal dominant Uncertain:1
This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 6842 of the SYNE2 protein (p.Gly6842Ser). This variant is present in population databases (rs201538331, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SYNE2-related conditions. ClinVar contains an entry for this variant (Variation ID: 573384). 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 serine 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. -
