Genes affected
CAMTA1 (HGNC:18806): (calmodulin binding transcription activator 1) The protein encoded by this gene contains a CG1 DNA-binding domain, a transcription factor immunoglobulin domain, ankyrin repeats, and calmodulin-binding IQ motifs. The encoded protein is thought to be a transcription factor and may be a tumor suppressor. However, a translocation event is sometimes observed between this gene and the WWTR1 gene, with the resulting WWTR1-CAMTA1 oncoprotein leading to epithelioid hemangioendothelioma, a malignant vascular cancer.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2022The c.109A>G (p.I37V) alteration is located in exon 2 (coding exon 2) of the CAMTA1 gene. This alteration results from a A to G substitution at nucleotide position 109, causing the isoleucine (I) at amino acid position 37 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
