Genes affected

ANTXR1 (HGNC:21014): (ANTXR cell adhesion molecule 1) This gene encodes a type I transmembrane protein and is a tumor-specific endothelial marker that has been implicated in colorectal cancer. The encoded protein has been shown to also be a docking protein or receptor for Bacillus anthracis toxin, the causative agent of the disease, anthrax. The binding of the protective antigen (PA) component, of the tripartite anthrax toxin, to this receptor protein mediates delivery of toxin components to the cytosol of cells. Once inside the cell, the other two components of anthrax toxin, edema factor (EF) and lethal factor (LF) disrupt normal cellular processes. Three alternatively spliced variants that encode different protein isoforms have been described. [provided by RefSeq, Oct 2008]

The ANTXR1 c.1435-12A>G variant is predicted to interfere with splicing. This variant was reported in the homozygous state in an individual with autosomal recessive GAPO syndrome (Stránecký et al. 2013. PubMed ID: 23602711). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. Although we suspect that this variant could be pathogenic for ANTXR1-related autosomal recessive disease, at this time, the clinical significance of this variant is uncertain due to insufficient functional and genetic evidence. The clinical significance of this variant in relation to autosomal dominant susceptibility to infantile capillary hemangioma is uncertain. -
