Genes affected

CAMTA2 (HGNC:18807): (calmodulin binding transcription activator 2) The protein encoded by this gene is a member of the calmodulin-binding transcription activator protein family. Members of this family share a common domain structure that consists of a transcription activation domain, a DNA-binding domain, and a calmodulin-binding domain. The encoded protein may be a transcriptional coactivator of genes involved in cardiac growth. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Jan 2010]

The c.2927G>T (p.R976L) alteration is located in exon 17 (coding exon 17) of the CAMTA2 gene. This alteration results from a G to T substitution at nucleotide position 2927, causing the arginine (R) at amino acid position 976 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
