Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_182961.4(SYNE1):c.25241C>T(p.Thr8414Met) variant causes a missense change. The variant allele was found at a frequency of 0.0000415 in 1,614,004 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. T8414T) has been classified as Likely benign.

Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is higher than would generally be expected for pathogenic variants in this gene. (http://gnomad.broadinstitute.org) Polyphen and MutationTaster yielded discordant predictions regarding whether this amino acid change is damaging to the protein. -
Autosomal recessive ataxia, Beauce type;C2751807:Emery-Dreifuss muscular dystrophy 4, autosomal dominant Uncertain:1
This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 8366 of the SYNE1 protein (p.Thr8366Met). This variant is present in population databases (rs759512753, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with SYNE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 538403). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The methionine 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. -
