Gene Polymorphisms, Skin Barrier, and Inflammation in Acne

Participants were genotyped for the MMP-2 rs243865 polymorphism. Genomic DNA was extracted from peripheral blood, and the specific genotype (CC, CT, or TT) was determined using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) analysis. This allowed for the stratification of participants based on their genetic variation at this locus for subsequent association analysis.

Participants were genotyped for the TIMP-2 rs8179090 polymorphism. Genomic DNA was extracted from peripheral blood, and the specific genotype (CC, GC, or GG) was determined using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) analysis. This allowed for the stratification of participants based on their genetic variation at this locus for subsequent association analysis.
