Genes affected

CCM2 (HGNC:21708): (CCM2 scaffold protein) This gene encodes a scaffold protein that functions in the stress-activated p38 Mitogen-activated protein kinase (MAPK) signaling cascade. The protein interacts with SMAD specific E3 ubiquitin protein ligase 1 (also known as SMURF1) via a phosphotyrosine binding domain to promote RhoA degradation. The protein is required for normal cytoskeletal structure, cell-cell interactions, and lumen formation in endothelial cells. Mutations in this gene result in cerebral cavernous malformations. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Nov 2009]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000521 (59/113346) while in subpopulation AFR AF= 0.00184 (52/28288). AF 95% confidence interval is 0.00144. There are 3 homozygotes in gnomad4. There are 24 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.

BS2

High AC in GnomAd4 at 59 AD gene.
