Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2 PP2 BP4_Moderate

The NM_182961.4(SYNE1):​c.7854C>G​(p.Ser2618Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,836 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. S2618S) has been classified as Benign.

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]

SYNE1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• 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=0.15894508).
