For the first time, we demonstrate a tissue-specific methylation pattern of SRD5A2 promoter in PFS patients.

For the first time, we demonstrate a tissue-specific methylation pattern of SRD5A2 promoter in PFS patients [which] could represent an important mechanism of neuroactive steroid levels and behavioral disturbances previously described in PFS… The SRD5A2 promoter was more frequently methylated in the CSF of PFS patients compared to controls (56.3 versus 7.7%).
