Sex-specific expression of genes mapped to Parkinson’s disease loci. (A) Sex-specific expression of genes mapped to Parkinson’s disease loci in the superior frontal cortex of neuropathologically healthy donors: [A(i)] LRRK2 (rs76904798 and rs34637584) and [A(ii)] PAM (rs26431) show higher expression levels in females (F) compared to males (M). [A(iii)] ITPKB (rs4653767) shows lower expression levels in females (F) compared to males (M). (B) Genes showing a sex-specific allelic effect/expression quantitative trait loci (eQTL) and a statistically different direction in the two sexes: [B(i)] KCNIP3 (rs2042477) and [B(ii)] GALC (rs979812). (C) Of the nine genes with statistically significant different age-related expression between the sexes, NUCKS1 sex-specific age-related expression is associated with the rs823118 genotype in [C(i)] females but not [C(ii)] males. A = adenine; C = cytosine; G = guanine; T = thymine.
