Some people consider prominent collarbones to be a beautiful feature of the human body. international classification of the Ehlers-Danlos syndromes. These changes in collagen increase the risk of blood vessel and organ rupture, and the other abnormalities that can occur with the classical and vascular types of Ehlers-Danlos syndrome. family of tumors: from ring chromosomes to tyrosine kinase inhibitor treatment. 2. Cleidocranial dysplasia (CCD) is typically caused by changes (mutations) in the RUNX2 gene.This gene gives the body instructions to make a protein used in the development and maintenance of bone and cartilage. CBFA1 is vital for differentiation of stem cells into osteoblasts, so any defect in this gene will cause defects in membranous and endochondral bone formation. The collarbones are either only partially developed or absent, causing the shoulders to slope toward each other in the front of the body. [25], Sibling actress-singers Abigail and Milly Shapiro were born with cleidocranial dysplasia, a trait they share with their mother.[26][27]. collagen that affect the processing of the amino-propeptide result in an Wormian bones can sometimes be observed in the skull.
