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 -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.11928645).

BS1

Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.0000329 (48/1460086) while in subpopulation AFR AF = 0.00003 (1/33322). AF 95% confidence interval is 0.0000166. There are 0 homozygotes in GnomAdExome4. There are 29 alleles in the male GnomAdExome4 subpopulation. Median coverage is 37. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome4 at 48 AD,Unknown gene.
