Genes affected

CD2BP2 (HGNC:1656): (CD2 cytoplasmic tail binding protein 2) This gene encodes a bi-functional protein. In the cytoplasm, the encoded protein binds the cytoplasmic tail of human surface antigen CD2 via its C-terminal GYF domain, and regulate CD2-triggered T lymphocyte activation. In the nucleus, this protein is a component of the U5 small nuclear ribonucleoprotein complex and is involved in RNA splicing. A pseudogene has been identified on chromosome 7. Alternative splicing results in multiple transcript variants but their biological validity has not been determined. [provided by RefSeq, Nov 2008]

Ambry Genetics

May 02, 2024

The c.560G>A (p.R187K) alteration is located in exon 5 (coding exon 4) of the CD2BP2 gene. This alteration results from a G to A substitution at nucleotide position 560, causing the arginine (R) at amino acid position 187 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
