Genes affected

CAP2 (HGNC:20039): (cyclase associated actin cytoskeleton regulatory protein 2) This gene was identified by its similarity to the gene for human adenylyl cyclase-associated protein. The function of the protein encoded by this gene is unknown. However, the protein appears to be able to interact with adenylyl cyclase-associated protein and actin. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.703C>G (p.P235A) alteration is located in exon 8 (coding exon 7) of the CAP2 gene. This alteration results from a C to G substitution at nucleotide position 703, causing the proline (P) at amino acid position 235 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
