Exploring Links with Rare Variants, COVID-19, and Short Anagen Hair Syndrome

This study investigates the genetic factors contributing to male pattern hair loss (MPHL) and its potential associations with COVID-19 and short anagen hair syndrome (SAH). Utilizing data from the UK Biobank, the research identifies rare variants in five genes (WNT10A, EDA2R, HEPH, CEPT1, EIF3F) linked to MPHL, including both previously known and novel candidates. Contrary to earlier studies, no genetic or epidemiological correlation between MPHL and severe COVID-19 was found. However, shared genetic determinants between MPHL and SAH were identified in the WNT10A gene. These findings enhance the understanding of MPHL genetics and its connections to other dermatological conditions.
