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.

Computational evidence support a benign effect (BayesDel_noAF=-0.57).

BP6

Variant 1-7665115-G-A is Benign according to our data. Variant chr1-7665115-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 210560.

BP7

Synonymous conserved (PhyloP=-2.16 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000125 (19/152104) while in subpopulation NFE AF = 0.00025 (17/67992). AF 95% confidence interval is 0.000159. There are 0 homozygotes in GnomAd4. There are 10 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 19 AD gene.
