This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

This study found pathogenic mutations in genes EDA, EDA1R, and EDARADD in 101 out of 124 hypohidrotic ectodermal dysplasia patients, revealing 23 novel mutations and indicating genetic variability.

This study identified a specific SNP in the CACNB4 gene associated with a higher risk of chemotherapy-induced alopecia in breast cancer patients, which may help develop interventions to improve their quality of life.

This study identified novel genetic associations with skin phenotypes such as age-spots, freckles, and hair characteristics in Japanese women, providing insights into the genetic basis of these traits.

This study found that an SNP in the FGFR2 gene, rs4752566, was significantly associated with hair thickness in Asian populations, suggesting an effect on hair morphology through altered FGFR2 expression levels.

In this study, researchers identified 18 genetic associations with scalp and facial hair traits in Latin Americans, including novel loci for hair greying and balding, with implications for understanding hair evolution.

This study found that the EDAR 1540T/C genetic variant is significantly associated with hair thickness variation in Japanese populations, enhancing previously observed associations in Southeast Asian groups.

This review discusses the unique characteristics and disorders of Asian hair, emphasizing the need for more comprehensive studies in this area.

This study found that specific DNA variants in the TCHH, WNT10A, and FRAS1 genes are associated with predicting straight hair in Europeans, showing high sensitivity but low specificity, especially using a neural networks approach.

This study demonstrated that genetic markers can predict human ear morphology with moderate to good accuracy, potentially aiding forensic identification in crime scene investigations where traditional DNA matches are unavailable.

This chapter discusses genetic polymorphisms related to phenotypes that differentiate between populations and reports no new results; it highlights the role of DNA technology in understanding human adaptation history.

This study found that both genetic and epigenetic factors significantly influence age-related facial skin aging, with lifestyle and environmental factors also playing a substantial role.

This review highlights how the development of forensic DNA phenotyping systems like IrisPlex, HIrisPlex, and HIrisPlex-S has advanced criminal investigation by accurately predicting physical traits such as eye, hair, and skin color from DNA, thereby improving the precision and relevance of forensic applications.

This study found that specific polymorphisms in the VDR gene, Taq1, and Cdx1, were significantly associated with increased risk of chronic telogen effluvium in women.

This study outlines the temporary or sometimes permanent hair loss caused by cancer treatments, noting it often starts 2-3 weeks after chemotherapy and highlights the need for more research into prevention and treatment strategies for therapy-related alopecia.

This study concluded that allele-specific PCR (AS-PCR) is more reliable than tetra-primer ARMS-PCR for genotyping the SNP rs1998076 due to better stability and interpretability.

This study found that the CYP3A4 rs4646437 genotype was significantly associated with ALT elevation in Japanese patients undergoing asunaprevir plus daclatasvir therapy for chronic HCV infection, suggesting genotyping may help in monitoring patients safely.

In this study, the rs4541843 G > A variant was found to be significantly associated with increased risk and severity of alopecia areata, as well as elevated expression of hsa-miR-182-5p, suggesting their potential as molecular markers for diagnosis and severity assessment.

This review summarizes advancements in forensic DNA phenotyping for appearance, ancestry, and age prediction from crime scene samples, reporting no new research findings but highlighting areas needing further research and validation.

This study found significant racial and ethnic disparities in the incidence and psychological impact of chemotherapy-related alopecia, with Asian women experiencing the greatest burden, highlighting the need for personalized and culturally sensitive care.

In this study, researchers identified three novel genetic loci associated with androgenetic alopecia, including one with significant association in females only, which may indicate a role for sex-specific genetic factors in patterned hair loss.
