Symptoms start gradually, sometimes with a barely noticeable tremor in just one hand. Tremor is common, and the disorder also commonly causes stiffness and slowing of movements. More than 10 million people worldwide are living with PD and the incidence increases dramatically with age.

Women who have had one ovary surgically removed (unilateral oophorectomy) are less likely to become pregnant after in vitro fertilisation and give birth to fewer babies than women with both ovaries. That is according to an extensive meta-analysis published in the journal Fertility and Sterility by researchers at Karolinska Institutet.

Scientists at Karolinska Institutet have now developed new high-precision tools able to identify what these noncoding sequences do. The study, which is published in the journal Nature Genetics, may eventually contribute to the development of new, targeted drugs.
