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

Verdict is Likely_benign. 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=0.09563011).
• BP6: Variant 6-152318249-T-G is Benign according to our data. Variant chr6-152318249-T-G is described in ClinVar as [Likely_benign]. Clinvar id is 262167.Status of the report is criteria_provided_single_submitter, 1 stars.
