Genes affected

SYNE2 (HGNC:17084): (spectrin repeat containing nuclear envelope protein 2) The protein encoded by this gene is a nuclear outer membrane protein that binds cytoplasmic F-actin. This binding tethers the nucleus to the cytoskeleton and aids in the maintenance of the structural integrity of the nucleus. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.011950374).

BP6

Variant 14-64027678-A-G is Benign according to our data. Variant chr14-64027678-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 283408.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000525 (8/152334) while in subpopulation SAS AF = 0.00166 (8/4832). AF 95% confidence interval is 0.000824. There are 1 homozygotes in GnomAd4. There are 6 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 8 Unknown,AD gene.
