Variant summary
Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBS1_SupportingBS2
The NM_182914.3(SYNE2):c.11876C>T(p.Thr3959Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000118 in 1,613,980 control chromosomes in the GnomAD database, including 1 homozygotes. 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. T3959R) has been classified as Uncertain significance.

Emery-Dreifuss muscular dystrophy 5, autosomal dominant Uncertain:2
This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 3959 of the SYNE2 protein (p.Thr3959Ile). This variant is present in population databases (rs149790389, gnomAD 0.007%). 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: 470919). 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 tolerated. 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.
not specified Uncertain:1
The c.11876C>T (p.T3959I) alteration is located in exon 60 (coding exon 59) of the SYNE2 gene. This alteration results from a C to T substitution at nucleotide position 11876, causing the threonine (T) at amino acid position 3959 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
