Genes affected
JAM3 (HGNC:15532): (junctional adhesion molecule 3) Tight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. The protein encoded by this immunoglobulin superfamily gene member is localized in the tight junctions between high endothelial cells. Unlike other proteins in this family, the this protein is unable to adhere to leukocyte cell lines and only forms weak homotypic interactions. The encoded protein is a member of the junctional adhesion molecule protein family and acts as a receptor for another member of this family. A mutation in an intron of this gene is associated with hemorrhagic destruction of the brain, subependymal calcification, and congenital cataracts. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Apr 2011]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4
Computational evidence support a benign effect (REVEL=0.073).
BP6
Variant 11-134069076-C-T is Benign according to our data. Variant chr11-134069076-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 1186860.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00393 (599/152338) while in subpopulation AFR AF = 0.0136 (567/41584). AF 95% confidence interval is 0.0127. There are 7 homozygotes in GnomAd4. There are 293 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 7 AR gene
