Genes affected
SYNE1 (HGNC:17089): (spectrin repeat containing nuclear envelope protein 1) This gene encodes a spectrin repeat containing protein expressed in skeletal and smooth muscle, and peripheral blood lymphocytes, that localizes to the nuclear membrane. Mutations in this gene have been associated with autosomal recessive spinocerebellar ataxia 8, also referred to as autosomal recessive cerebellar ataxia type 1 or recessive ataxia of Beauce. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SYNE1. . Gene score misZ -0.29069 (greater than the threshold 3.09). Trascript score misZ 3.2909 (greater than threshold 3.09). GenCC has associacion of gene with autosomal recessive ataxia, Beauce type, autosomal recessive myogenic arthrogryposis multiplex congenita, Emery-Dreifuss muscular dystrophy 4, autosomal dominant, arthrogryposis multiplex congenita 3, myogenic type, autosomal dominant Emery-Dreifuss muscular dystrophy.
BP4
Computational evidence support a benign effect (MetaRNN=0.358594).
BS2
High AC in GnomAd4 at 13 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Uncertain significance, criteria provided, single submitterclinical testingInvitaeJul 11, 2022This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 3095 of the SYNE1 protein (p.Ala3095Thr). This variant is present in population databases (rs398123005, gnomAD 0.01%). This missense change has been observed in individual(s) with spastic paraplegia, mild intellectual disability, axonal neuropathy, and leukoencephalopathy in a (PMID: 24123876). This variant is also known as Ala3088Thr. ClinVar contains an entry for this variant (Variation ID: 242649). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. -
