Abstract

Background: Androgenetic alopecia (AGA) is a common form of hair loss which inflicts progressive hair loss leading to various patterns. The cause of this disease is believed to be multifactorial, which is majorly attributed to genetic and non-genetic factors. This pilot study aimed to investigate the association of rs6152 allele, a SNP on AR gene, with AGA, as well as explore other contributing factors in the Indonesian local population. Methods: In this cross-sectional study, a total of 100 participants, which categorized into alopecia subjects and non-alopecia subjects, were enrolled for rs6152 SNPs detection. Anthropomorphic data such as height and weight, blood pressure and family history were obtained by measurement and questionnaire. Results: The study showed low frequency of individuals with rs6152 non-risk alleles (2%) and further analysis showed no significant association between rs6152 allele and AGA. However, familial history analysis revealed a strong association between family history and AGA risks. Additionally, age, gender, hypertension status and BMI were identified as significant factors associated (p-value < 0.05) with AGA. Conclusion: rs6152 was not a reliable genetic marker for AGA in the Indonesian local population. While familial history with AGA showed the inheritance pattern of autosomal dominant inheritance with sex limitation, non-genetic factors such as age, gender, hypertension status and BMI were strongly associated with AGA risk. This shows the complexity and multifactorial causes of AGA in the Indonesian local population.

Abstract

Background: Matrix metalloproteinase-1 (MMP-1) is an enzyme responsible for degrading extracellular matrix (ECM) components, particularly collagen. Overexpression of MMP-1 can accelerate ECM degradation, contributing to various pathological conditions. The most studied polymorphism in the promoter region of the MMP-1 gene is rs1799750, which has been linked to several diseases in previous studies. Androgenetic alopecia (AGA) is a condition characterized by the progressive miniaturization of hair follicles, influenced by androgen signaling and ECM remodeling. This study aimed to investigate the prevalence of MMP-1 gene polymorphism and its potential association with AGA.Materials and methods: This study included 50 subjects diagnosed with AGA and 50 subjects without AGA. All subjects completed a questionnaire that included gender, age, BMI, and ethnicity. DNA was extracted from blood samples for genotyping of the MMP-1 rs1799750 gene. Genotyping was performed using the PCR-RFLP method with AluI as the restriction enzyme. For validation, several samples were sequenced at Apical Scientific Laboratory, Malaysia.Results: Among the 50 subjects with AGA, 9 had the 1G/1G genotype, 26 had the 1G/2G genotype, and 15 had the 2G/2G genotype. Similarly, among the 50 subjects without AGA, 8 had the 1G/1G genotype, 27 had the 1G/2G genotype, and 15 had the 2G/2G genotype. The allele frequencies of 1G and 2G in the AGA group were 0.44 and 0.56, respectively, while in the non-AGA group, they were 0.43 and 0.57, respectively. Chi-square analysis of AGA and MMP-1 genotype yielded a p-value of 0.96, indicating no significant association between AGA and the MMP-1 genotype.Conclusion: In this study, the association between the MMP-1 gene polymorphisms rs1799750 with AGA was not observed.Keywords: Androgenetic Alopecia, matrix metalloproteinase-1, polymorphisms, rs1799750
