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 GeneticsJan 24, 2024The c.319C>G (p.Q107E) alteration is located in exon 6 (coding exon 6) of the RHOT2 gene. This alteration results from a C to G substitution at nucleotide position 319, causing the glutamine (Q) at amino acid position 107 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
