I have a friend whose dd has some form of chondrodysplasia. I'm not sure which one. She has uneven leg growth, no structure under her nose which makes the bridge of her nose flat, etc. My question is whether there are other issues that go along with it. This girl has had hair growth only under one arm since she was 3 or 4, bad BO at a young age, etc. I thought way back when that this was attributed to her chondrodysplasia? Now she has developed a hard breast bud underneath just one nipple with no sign of the other one even starting. I'm wondering if there is any conncection. My friend is worried about her dd.
