|MadSci Network: Genetics|
Frustration of the unknown - a hallmark of science. First of all, identical twins are only genetically identical - all the tiny differences that occur in a life make subtle differences crop up. What you describe is vexing - far beyond the usual differences that crop up between twins. A corellary question, is it possible they are fraternal twins, and just look a great deal alike? This is probably a dumb question, but I was just wondering. Second, as you probably know, alopecia is an autoimmune disease, where the immune system attacks the hair folicle/or hormones which trigger hair production - and the hair of the sufferer falls out. I would guess that twins should have the same amount of hair, unless one has an infection or was exposed to something (many autoimmune disease have environmental triggers.) I am not a medical doctor, and can't honestly offer you any medical advice. There is the ubiquitous webMD, and here are a few web sites: http://www.alopeciaareata.com/ http://npntserver.mcg.edu/html/alopecia/AlopeciaFAQ%28part01%29.html http://www.follicle.com/ I can vouch for none of them - Finally, from personal experience, I know a family where two of four daughters suffered from alopecia in their pre teens, but the condition cleared up by the time they were 14 or so. It's a strange malady. Good luck, and ask your doctor lots of questions - you deserve all the answers you desire! Regards Tod Companion, Ph.D.
