Variant summary
Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBS1_SupportingBS2
The NM_182914.3(SYNE2):c.20519T>A(p.Val6840Asp) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000041 in 1,461,832 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. 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. V6840G) has been classified as Uncertain significance.

Submissions by phenotype
Emery-Dreifuss muscular dystrophy 5, autosomal dominant Uncertain:1
This sequence change replaces valine with aspartic acid at codon 6840 of the SYNE2 protein (p.Val6840Asp). The valine residue is weakly conserved and there is a large physicochemical difference between valine and aspartic acid. This variant is present in population databases (rs758858068, ExAC 0.01%). This variant has not been reported in the literature in individuals with SYNE2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. -
