Genes affected

REM1 (HGNC:15922): (RRAD and GEM like GTPase 1) The protein encoded by this gene is a GTPase and member of the RAS-like GTP-binding protein family. The encoded protein is expressed in endothelial cells, where it promotes reorganization of the actin cytoskeleton and morphological changes in the cells. [provided by RefSeq, Jul 2008]

Ambry Genetics

May 29, 2024

The c.667G>C (p.E223Q) alteration is located in exon 5 (coding exon 4) of the REM1 gene. This alteration results from a G to C substitution at nucleotide position 667, causing the glutamic acid (E) at amino acid position 223 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
