This study identified a high-riskallele in the PLCD1 gene associated with hereditary trichilemmal cyst formation, proposing a monoallelic two-hit mechanism as the underlying genetic pathogenesis.
August 2015 in “International Journal of Genetics and Molecular Biology”
This study found that specific Y-chromosome alleles may influence susceptibility to prostate cancer in Iraqi males, suggesting their potential use in screening for the disease.
April 2017 in “Journal of Investigative Dermatology”
This study found that the PON1 192 R allele was associated with an increased risk of psoriasis and altered lipid profiles in patients from Western Mexico.
In their study, Tim Spector and colleagues identified a new genetic association at chromosome 20p11.22 with male-pattern baldness, confirmed by the increased risk when combined with a known androgen receptor gene variant.
Hair loss may be linked to the GPR133 receptor, independent of the androgen receptor pathway. Treatments like finasteride, dutasteride, minoxidil, RU58841, and KX-826 show varying results, with hair loss persisting due to high testosterone and GPR133's role.
Finasteride is effective for DHT/AR-driven hair loss but not for chromosome 20-driven cases, where treatments like minoxidil, prostaglandin analogs, and low-level laser therapy may be more beneficial. Genetic testing can help determine the underlying cause of hair loss to tailor treatment effectively.
Finasteride users discuss potential side effects, including Post Finasteride Syndrome (PFS), with varying opinions on its legitimacy and impact. Some users report side effects like changes in semen consistency and reduced pre-ejaculate, while others emphasize the rarity and reversibility of side effects.
Finasteride and dutasteride are still available in the EU, with a warning about potential suicidal thoughts. The benefits of these treatments are deemed greater than the risks.
Athletes often use finasteride to maintain hair transplants, but some avoid it due to potential hormonal effects. Notable examples include Mo Salah and Conor McGregor, while LeBron James has had multiple procedures with varying success.
