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]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.50G>A (p.R17H) alteration is located in exon 2 (coding exon 1) of the CAP2 gene. This alteration results from a G to A substitution at nucleotide position 50, causing the arginine (R) at amino acid position 17 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.Arg17Hisvariant in the CAP2gene has not been previously reported in association with disease. This varianthas been identified in 5/251,492chromosomes by the Genome Aggregation Database (http://gnomad.broadinstitute.org/). Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. Computational tools do not predict that the p.Arg17His variant impacts protein function; however, the accuracy of in silicoalgorithms is limited. These data were assessed using the ACMG/AMP variant interpretation guidelines. In summary, the significance of thep.Arg17Hisvariant is uncertain.Additional information is needed to resolve the significance of this variant. [ACMG evidence codes used:PM2] -
