Genes affected

AMOTL1 (HGNC:17811): (angiomotin like 1) The protein encoded by this gene is a peripheral membrane protein that is a component of tight junctions or TJs. TJs form an apical junctional structure and act to control paracellular permeability and maintain cell polarity. This protein is related to angiomotin, an angiostatin binding protein that regulates endothelial cell migration and capillary formation. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]

The c.323G>A (p.R108Q) alteration is located in exon 3 (coding exon 3) of the AMOTL1 gene. This alteration results from a G to A substitution at nucleotide position 323, causing the arginine (R) at amino acid position 108 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
