Genes affected

CABP2 (HGNC:1385): (calcium binding protein 2) This gene belongs to a subfamily of calcium binding proteins that share similarity to calmodulin. Like calmodulin, these family members can likely stimulate calmodulin-dependent kinase II and the protein phosphatase calcineurin. Calcium binding proteins are an important component of calcium mediated cellular signal transduction. Two transcript variants encoding different isoforms have been found for this gene.

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. This variant has not been reported in the literature in individuals affected with CABP2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change falls in intron 6 of the CABP2 gene. It does not directly change the encoded amino acid sequence of the CABP2 protein. It affects a nucleotide within the consensus splice site. -
