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]

The c.124G>A (p.V42M) alteration is located in exon 3 (coding exon 2) of the CAP2 gene. This alteration results from a G to A substitution at nucleotide position 124, causing the valine (V) at amino acid position 42 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
