research Genetic association of HLA‐DQB1 and HLA‐DRB1 polymorphisms with alopecia areata in the Italian population

35 citations , June 2011 in “British Journal of Dermatology”

This study found that in an Italian population, the HLA-DQB1*03 allele was associated with increased susceptibility to alopecia areata, particularly in cases with more than 50% hair loss.

Association of Psoriasis and Psoriatic Arthritis with Human Leukocyte Antigen and Killer Cell Immunoglobulin-Like Receptor Gene Frequency: A Multiethnic Population Study

research Association of psoriasis and psoriatic arthritis with human leukocyte antigen and killer cell immunoglobulin–like receptor gene frequency: A multiethnic population study

February 2009 in “Journal of The American Academy of Dermatology”

Certain immune system genes are linked to a higher risk of psoriasis and psoriatic arthritis, while others may offer protection.

research Human Leukocyte Antigen Class II Alleles Are Associated with Risk of Alopecia Areata

36 citations , July 2007 in “Journal of Investigative Dermatology”

This study observed a strong negative association between the HLA-DQB1*0201 allele and the alopecia totalis/alopecia universalis phenotype in Caucasian individuals, indicating a potential protective role.

research The genetic basis of dermatophytosis skin infection susceptibility

March 2026 in “Nature Communications”

In this study, researchers conducted a large genome-wide association meta-analysis and found 30 significant genetic loci linked to the risk of dermatophytosis, shedding light on the roles of keratin biology, skin barrier defects, immune dysfunction, and obesity in the disease.
