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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=3.0537154E-5).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.684 is higher than 0.05.
