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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2023The c.151G>A (p.V51M) alteration is located in exon 3 (coding exon 3) of the RHOT2 gene. This alteration results from a G to A substitution at nucleotide position 151, causing the valine (V) at amino acid position 51 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
