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]

Jun 17, 2024

The c.443C>T (p.S148L) alteration is located in exon 8 (coding exon 8) of the RHOT2 gene. This alteration results from a C to T substitution at nucleotide position 443, causing the serine (S) at amino acid position 148 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
