Dr. Bernstein Featured in Huffington Post on Hair Loss Genetics

Huffington Post on Hair Loss GeneticsDr. Bernstein addresses the common myth that hair loss is inherited exclusively from the mother’s side of the family – and, more specifically, from your mother’s father. While your mother’s (or maternal grandfather’s) genes can be the culprit, the characteristics of your hair are influenced by many different genes that may come from either or both sides of your family.

Study More Accurately Predicts Severe Balding Risk Using New Genetic Profile

What are the chances that I will go bald? How bald will I be? Can I know for sure? These are among the most common questions we get from patients in our hair loss consultations. Despite extensive knowledge about the mechanisms and causes of androgenetic alopecia (common baldness), the answers to these questions have been a bit hazy. New research has sharpened the focus on the genetic mix that results in hair loss and has enabled more accurate predictions. A study published in February 2017 in the journal PLoS Genetics identified over 250 gene locations newly linked to hair loss. Using this information, researchers more accurately predicted severe balding compared to previous methods.

Is Genetic Hair Loss Linked to Other Diseases?

Q: There was a retrospective study by Lotufo et al. linking male pattern baldness to heart disease. Do you think there are other links like this for androgenetic alopecia?

A: Family studies revealed both the androgen receptor locus on the X chromosome, as well as a new locus on chromosome 3q26. Association studies performed in two independent groups revealed a locus on chromosome 20 (not near any known genes) as well as the androgen receptor on the X chromosome. Read on for the rest of the answer.

Is Genetic Test for Hair Loss Worthwhile?

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.

Dr. Bernstein Answers Questions On HairDX Genetic Test To Predict Hair Loss

The HairDX genetic test for hair loss offers information that can aid you and your doctor in making an informed decision about the treatment of your hair loss. It offers one more bit of information that, in the context of other data (such as hair loss pattern, scalp miniaturization and family history) can help guide you and your doctor to formulate an appropriate treatment plan. How does it work? How accurate is the test? How does the test compare to information obtained from a history and physical exam by your physician? Dr. Bernstein answers these questions and more on the HairDX genetic test for hair loss.

Research Groups Explore Genetics Of Balding

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.
