Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_182961.4(SYNE1):c.18680G>T(p.Arg6227Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000186 in 1,614,048 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 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. R6227W) has been classified as Uncertain significance.

ClinVar contains an entry for this variant (Variation ID: 290593). This missense change has been observed in individual(s) with clinical features of spinocerebellar ataxia (PMID: 32889669). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (no rsID available, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 6156 of the SYNE1 protein (p.Arg6156Leu). 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: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25"). 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. -
