androgenetic alopecia androgen receptor ectodysplasin A2 receptor AGA AR EDA2R 57K mutation male pattern baldness

Studysummary This study suggests that the AGA risk haplotype in Europeans was driven to high frequency by positive selection, likely associated with a variant in the EDA2R gene.

Research cited in this study

15 / 15 results

research Susceptibility Variants for Male-Pattern Baldness on Chromosome 20p11

140 citations , October 2008 in “Nature Genetics”

research Male-Pattern Baldness Susceptibility Locus at 20p11

111 citations , October 2008 in “Nature Genetics”

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.

research Enhanced Ectodysplasin-A Receptor Signaling Alters Multiple Fiber Characteristics to Produce the East Asian Hair Form

98 citations , June 2008 in “Human mutation”

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.

research EDA2R Is Associated With Androgenetic Alopecia

82 citations , April 2008 in “Journal of Investigative Dermatology”

EDA2R gene linked to hair loss.

research Genome-Wide Scan and Fine-Mapping Linkage Study of Androgenetic Alopecia Reveals a Locus on Chromosome 3q26

62 citations , March 2008 in “American Journal of Human Genetics”

This study located a potential genetic link for androgenetic alopecia on chromosome 3q26, marking an early step in identifying new susceptibility genes for male pattern baldness.

research Hormonal Regulation of Hair Follicles Exhibits a Biological Paradox

98 citations , February 2007 in “Seminars in Cell & Developmental Biology”

This review explores the hormonal regulation of hair growth and changes with season, age, and sexual development, and calls for improved treatments for hair disorders.

Baldness And The Androgen Receptor: The AR Polyglycine Repeat Polymorphism Does Not Confer Susceptibility To Androgenetic Alopecia

research Baldness And The Androgen Receptor: The AR Polyglycine Repeat Polymorphism Does Not Confer Susceptibility To Androgenetic Alopecia

60 citations , January 2007 in “Human Genetics”

In this study, researchers found that while the SNP rs6152 is strongly associated with androgenetic alopecia, the GGN triplet repeat is not, suggesting the causative variant is likely a non-coding one.

research Edar Signaling in the Control of Hair Follicle Development

71 citations , November 2005 in “The journal of investigative dermatology. Symposium proceedings/The Journal of investigative dermatology symposium proceedings”

This review discusses the role of Edar signaling in hair follicle development and cycling, emphasizing its impact on cell fate, differentiation, and interactions with other pathways, but reports no new results.

research Genetic Variation in the Human Androgen Receptor Gene Is the Major Determinant of Common Early-Onset Androgenetic Alopecia

195 citations , June 2005 in “American Journal of Human Genetics”

Genetic variation in the androgen receptor gene mainly causes early-onset hair loss, with maternal inheritance playing a key role.

The E211 G>A Androgen Receptor Polymorphism Is Associated With a Decreased Risk of Metastatic Prostate Cancer and Androgenetic Alopecia

research The E211 G>A Androgen Receptor Polymorphism Is Associated With a Decreased Risk of Metastatic Prostate Cancer and Androgenetic Alopecia

76 citations , April 2005 in “Cancer Epidemiology, Biomarkers & Prevention”

This study found that the AR-E211 A allele is associated with a lower risk of both metastatic prostate cancer and androgenetic alopecia in an Australian population.
