Genes affected

RAB36 (HGNC:9775): (RAB36, member RAS oncogene family) Predicted to enable GTP binding activity and GTPase activity. Predicted to be involved in protein transport. Predicted to be located in Golgi membrane. [provided by Alliance of Genome Resources, Apr 2022]

RAB36 links:

RSPH14 (HGNC:13437): (radial spoke head 14 homolog) This gene encodes a protein with no known function but with slight similarity to a yeast vacuolar protein. The gene is located in a region deleted in pediatric rhabdoid tumors of the brain, kidney and soft tissues, but mutations in this gene have not been associated with the disease.
