Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PP2PP5BP4BS2_Supporting

The NM_182961.4(SYNE1):c.10727G>A(p.Arg3576Gln) variant causes a missense change. The variant allele was found at a frequency of 0.00000752 in 1,461,892 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R3576W) has been classified as Uncertain significance.

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 Uncertain_significance. Variant got 0 ACMG points.

PP2

Missense variant where missense usually causes diseases, SYNE1

PP5

Variant 6-152354858-C-T is Pathogenic according to our data. Variant chr6-152354858-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 402199.We mark this variant Likely_pathogenic, oryginal submissions are: {Likely_pathogenic=1, Uncertain_significance=2}. Variant chr6-152354858-C-T is described in Lovd as [Pathogenic].

BP4

Computational evidence support a benign effect (MetaRNN=0.20275581). . Strength limited to SUPPORTING due to the PP5.

BS2

High AC in GnomAdExome4 at 11 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
