Genes affected

RHOT2 (HGNC:21169): (ras homolog family member T2) This gene encodes a member of the Rho family of GTPases. The encoded protein is localized to the outer mitochondrial membrane and plays a role in mitochondrial trafficking and fusion-fission dynamics. [provided by RefSeq, Nov 2011]

Ambry Genetics

Oct 01, 2024

The c.213G>C (p.E71D) alteration is located in exon 4 (coding exon 4) of the RHOT2 gene. This alteration results from a G to C substitution at nucleotide position 213, causing the glutamic acid (E) at amino acid position 71 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
