PARK2 (OMIM *602544) is the parkin gene that may cause a form of autosomal recessive juvenile Parkinson disease (OMIM 600116) due to a mutation in the parkin protein. This form of genetic mutation may be one of the most common known genetic causes of early-onset Parkinson disease.In one study of patients with onset of Parkinson disease prior to age 40 (10% of all PD patients), 18% had parkin mutations, with 5% homozygous mutations.his form of genetic mutation may be one of the most common known genetic causes of early-onset Parkinson disease.

The HER2 gene codes for a receptor on the surface of some cancer cells, human epidermal growth factor receptor 2.These cancer cells may contain more than the usual two copies of the HER2 gene which can lead to overproduction of the receptors that are displayed on the cell's surface.Excess presence of these receptors leads to a more aggressive form of breast cancer that grows more quickly than other forms of cancer. HER2 positivity is indicated if there are more than six copies of the HER2 gene per cell or if more than 2.2 HER2 genes are found for each copy of chromosome 17. 2  The latter is termed the HER2 chromosome enumeration probe 17 or the CEP17 ratio.
