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.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CAMTA1. . Gene score misZ 3.2619 (greater than the threshold 3.09). Trascript score misZ 4.755 (greater than threshold 3.09). GenCC has associacion of gene with cerebellar dysfunction with variable cognitive and behavioral abnormalities.
