Question: Is Ehlers-Danlos syndrome, progeroid type inherited ?
Answer: How is Ehlers-Danlos syndrome progeroid type inherited? Ehlers-Danlos syndrome progeroid type is inherited in an autosomal recessive pattern. This means that an individual must have two non-functional copies of the B4GALT7 gene to be affected with the condition. One copy is inherited from each parent. If an individual has only one non-functional B4GALT7 gene (such as each parent), he or she is a "carrier". Carriers do not typically show any signs or symptoms of a recessive condition. When two carriers for a recessive condition have children, with each pregnancy there is a 25% (1 in 4) risk for the child to be affected, a 50% (1 in 2) risk for the child to be a carrier (like each parent) and a 25% risk that the child will be unaffected and also not be a carrier. An individual with a recessive condition will generally have unaffected children, except in the rare circumstance where his or her partner is a carrier of a nonfunctional B4GALT7 gene.
