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]

Ambry Genetics

Feb 17, 2024

The c.159G>A (p.M53I) 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 159, causing the methionine (M) at amino acid position 53 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
