A composite measure of gender and its association with sex, common somatic symptoms and health care seeking in the general population cohort Lifelines, part 1
The first aim of this study is to calculate a gender-index (based on a Lasso regression with sex as an outcome) within Lifelines and relate it to sex. We therefore need the CNV of the sex chromosomes of all participants, the presence or absence of SRY-gene deletion/duplication/translocation and the CNV of the NROB1/DAX1 gene
