MONDAY, Sept. 9 (HealthDay News) — A genetic deletion may be linked to some cases of early onset Parkinson’s disease, researchers say.
The investigators found that people aged 35 to 64 who were missing DNA on a specific part of chromosome 22 were about 90 times more likely to develop Parkinson’s than people from the same age group in the general population.
People with this inherited genetic condition — called 22q11.2 deletion syndrome — have about 50 genes missing on chromosome 22. The condition occurs in about one in 2,000 to 4,000 people, and those with this genetic deletion may have birth defects (including heart defects), learning or speech difficulties, anxiety disorders, or schizophrenia.
Previously reported cases of patients with 22q11.2 deletion syndrome and Parkinson’s disease symptoms have indicated that there may be a link between the two conditions, according to the researchers from the Center for Addiction and Mental…
