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 GeneticsMar 07, 2024The c.118A>T (p.I40F) alteration is located in exon 3 (coding exon 3) of the RHOT2 gene. This alteration results from a A to T substitution at nucleotide position 118, causing the isoleucine (I) at amino acid position 40 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
