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 Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BP6: Variant 6-152256617-T-C is Benign according to our data. Variant chr6-152256617-T-C is described in ClinVar as [Benign]. Clinvar id is 262175.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr6-152256617-T-C is described in Lovd as [Benign]. Variant chr6-152256617-T-C is described in Lovd as [Likely_benign].
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.118 is higher than 0.05.
