Scientists have found that genes located on a single chromosome are responsible for the development of early male-pattern baldness. According to a study published in the Nature Genetics, six gene variants, all located on chromosome 20, are linked to male-pattern baldness, also known as androgenic alopecia. Findings revealed that these genes increase the risk of developing early baldness by seven-fold. Previous studies had reported that the androgen receptor gene on chromosome X, inherited from the mother, is the only gene responsible for male baldness.
The study showed that chromosome 20, however, has both maternal and paternal origins, indicating the cause of same hair loss patterns between fathers and sons. Scientists are optimistic that the early detection of these genes can help individuals seek treatment and tackle the condition in its early stages.
