Is Genetic Test for Hair Loss Worthwhile?

October 14th, 2009

Q: Is it worth getting the genetic test for balding?

A: You’re referring to Hair DX (hairdx.com), which costs about $150 and came to market in January of 2008 as the first test for androgenetic alopecia, aka male pattern baldness.

The test screens for variations in the androgen receptor gene on the X chromosome, the gene that is associated with male pattern hair loss. The purpose of the test is to identify persons at increased risk of developing hair loss before it is clinically apparent – so that medical intervention can be started early, when it is most effective.

Causes

July 28th, 2009

HAIR LOSS CONSULT By far the most common cause of hair loss in men is androgenetic alopecia, also referred to as “male pattern” or “common” baldness. It is caused by the effects of the male hormone dihydrotestosterone (DHT) on genetically susceptible scalp hair follicles. This sensitivity to DHT is present mainly in hair follicles that [...]

Research Groups Explore Genetics Of Balding

October 15th, 2008

We all have seen that some bald sons have bald fathers, even when no one on the mother’s side of the family has any hair loss. This suggests that the genetics of male pattern alopecia is more complicated, with multiple genes influencing hair growth. And it is likely that the inheritance of baldness is polygenetic, with relevant genes coming from both the x-chromosome of the mother and non-sex chromosomes of either parent. So where are the other genes?

Two independent research groups, one from England and the other Germany, both published in the journal Nature Genetics, have identified a gene locus p11 on chromosome 20 that seems to be correlated with male pattern hair loss, and since the gene is on a non-sex chromosome, it offers an explanation for why the inheritance of common baldness can be from either side of the family.
