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]

The c.608C>T (p.S203F) alteration is located in exon 5 (coding exon 4) of the CD2BP2 gene. This alteration results from a C to T substitution at nucleotide position 608, causing the serine (S) at amino acid position 203 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
