Bowing of The Long Bones

  • Molecular diagnosis is important for accurate prognosis and genetic counselling. COMP mutation is the most common form of MED in Western. But, MATN3 mutation was reported as the most common type of MED in Korea.[koreascience.or.kr]
  • Molecular analysis is likely to expand the clinical spectrum of MED and may also provide data relevant to prognosis and future therapeutic intervention. The overall incidence of MED is estimated to be 1 in 10,000 births.[eurofinsclinicalgenetics.co.in]
  • Prognosis [ 5 ] The age at diagnosis, natural progression of the disease, and severity of symptoms are determined by severity of disease, which may be associated with specific genetic mutations.[patient.info]
  • The nature of their genetic condition and any other health issues, how quickly the child is diagnosed, and possible treatment options, all factor into a child’s long-term prognosis.[chop.edu]
