Genes affected

OMG (HGNC:8135): (oligodendrocyte myelin glycoprotein) Predicted to enable identical protein binding activity. Predicted to be involved in neuron projection regeneration. Predicted to act upstream of or within regulation of collateral sprouting of intact axon in response to injury. Predicted to be located in plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

OMG links:

NF1 (HGNC:7765): (neurofibromin 1) This gene product appears to function as a negative regulator of the ras signal transduction pathway. Mutations in this gene have been linked to neurofibromatosis type 1, juvenile myelomonocytic leukemia and Watson syndrome. The mRNA for this gene is subject to RNA editing (CGA>UGA->Arg1306Term) resulting in premature translation termination. Alternatively spliced transcript variants encoding different isoforms have also been described for this gene. [provided by RefSeq, Jul 2008]
