Genes affected

PARK7 (HGNC:16369): (Parkinsonism associated deglycase) The product of this gene belongs to the peptidase C56 family of proteins. It acts as a positive regulator of androgen receptor-dependent transcription. It may also function as a redox-sensitive chaperone, as a sensor for oxidative stress, and it apparently protects neurons against oxidative stress and cell death. Defects in this gene are the cause of autosomal recessive early-onset Parkinson disease 7. Two transcript variants encoding the same protein have been identified for this gene.

The PARK7 c.-24+66C>G variant is located in the 5' untranslated region. This variant, also referred to as DJ-1 g.159C>G in the literature, has been reported in an individual with early onset Parkinson disease and was shown to segregate with disease in the family (Tarantino et al. 2009. PubMed ID: 18722801). This variant is reported in 0.0065% of alleles in individuals of European (non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
