Genes affected

RHOBTB3 (HGNC:18757): (Rho related BTB domain containing 3) Enables ATP binding activity and small GTPase binding activity. Involved in retrograde transport, endosome to Golgi. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]

RHOBTB3 links:

GLRX (HGNC:4330): (glutaredoxin) This gene encodes a member of the glutaredoxin family. The encoded protein is a cytoplasmic enzyme catalyzing the reversible reduction of glutathione-protein mixed disulfides. This enzyme highly contributes to the antioxidant defense system. It is crucial for several signalling pathways by controlling the S-glutathionylation status of signalling mediators. It is involved in beta-amyloid toxicity and Alzheimer's disease. Multiple alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Aug 2011]

Ambry Genetics

Nov 18, 2022

The c.1273G>A (p.E425K) alteration is located in exon 8 (coding exon 8) of the RHOBTB3 gene. This alteration results from a G to A substitution at nucleotide position 1273, causing the glutamic acid (E) at amino acid position 425 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
