Article examining the genetic connections from finasteride symptoms

Has there been any definitive studies done on which genes have an effect on post-finasteride syndrome (side effects that persist after discontinuation of Fin)?  ARTICLE:  https://www.smoa.jsexmed.org/article/S2050-1161(16)30075-7/abstract

Very interesting. I just read the full article and I will quote the last of the result analysis and the conclusion of the article. My interpretation suggests that the ability to detect men who might get PFS is not understood by any of the genetic findings of this report; however, there are some influences of symptoms reported by men who take finasteride as summarized below:

” A general limitation of this study work is that some symptoms reported by patients with PFS could not be objectively determined. Furthermore, the retrospective design of our study did not allow a clinical assessment of these men before finasteride use. Future studies are necessary to assess the AR genetic profile and testosterone levels in subjects who developed PFS compared with subjects who did not develop adverse symptoms after using finasteride against AGA. CONCLUSION Causes and predisposing factors responsible for the development of long-term adverse side effects in young men who used low-dose finasteride against AGA remain an enigma. Several symptoms were in common in more than 70% of patients with PFS, but a plethora of other disturbances was reported by a minority of patients, with some clearly related and some not to androgenicity. Our study showed that the length of two trinucleotide repeats in the AR gene contribute to the frequency of some specific symptoms reported by patients with PFS. The (CAG)n and (GGN)n polymorphisms were involved in two specific symptoms (ie, scrotal discomfort and increased skin dryness); for other symptoms, only one of the two polymorphisms was involved, which is likely a reflection of the complex modulation of AR activity.16,40 Our investigation using a precision medicine approach suggested genetic implications in symptoms of patients with PFS. Much more genetic and non-genetic research is necessary to elucidate the pathophysiologic pathways leading to the onset and persistence of adverse effects in former finasteride users.”
