Genes affected

CD2AP (HGNC:14258): (CD2 associated protein) This gene encodes a scaffolding molecule that regulates the actin cytoskeleton. The protein directly interacts with filamentous actin and a variety of cell membrane proteins through multiple actin binding sites, SH3 domains, and a proline-rich region containing binding sites for SH3 domains. The cytoplasmic protein localizes to membrane ruffles, lipid rafts, and the leading edges of cells. It is implicated in dynamic actin remodeling and membrane trafficking that occurs during receptor endocytosis and cytokinesis. Haploinsufficiency of this gene is implicated in susceptibility to glomerular disease. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.040625 fraction of the gene. Cryptic splice site detected, with MaxEntScore 6.5, offset of 15, new splice context is: tctactccttaatcctacAGtca. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 6-47576523-GC-CT is Pathogenic according to our data. Variant chr6-47576523-GC-CT is described in ClinVar as [Pathogenic]. Clinvar id is 5703.Status of the report is criteria_provided_single_submitter, 1 stars.
