Thus, it is possible that C19orf12 gene maps to the same metabolic pathway as PANK2 and PLA2G6. The C19orf12 gene abnormality should not be confused with disorders associated with mutation in the C9orf12 gene, located on chromosome 9 and associated with familial fronto-temporal dementia and motor neuron disease [123-125]. This evidence concerns the gene C19orf12 and motor neuron disorder.
