TLDR CYB5R1 and IL1A genes may be linked to different types of acne scars.
This study investigated genetic associations with acne scarring in 202 acne patients, revealing that CYB5R1 variants are potentially linked to atrophic scarring, while IL1A variants are associated with fibrotic scarring, including hypertrophic and keloid scars. No significant associations were found with the other genes studied (TNF, TLR4, FLG, and SPINK5). The findings suggest a polygenic nature of acne scarring, but further research with larger cohorts is needed for validation.
