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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.539G>A (p.R180Q) alteration is located in exon 4 (coding exon 3) of the REM1 gene. This alteration results from a G to A substitution at nucleotide position 539, causing the arginine (R) at amino acid position 180 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
