Genes affected

AMOTL2 (HGNC:17812): (angiomotin like 2) Angiomotin is a protein that binds angiostatin, a circulating inhibitor of the formation of new blood vessels (angiogenesis). Angiomotin mediates angiostatin inhibition of endothelial cell migration and tube formation in vitro. The protein encoded by this gene is related to angiomotin and is a member of the motin protein family. Alternative splicing results in multiple transcript variants of this gene.

The c.1780C>T (p.R594C) alteration is located in exon 7 (coding exon 6) of the AMOTL2 gene. This alteration results from a C to T substitution at nucleotide position 1780, causing the arginine (R) at amino acid position 594 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
