In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. X-linked recessive pattern of inheritance: The gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. X-Linked Tetra-Amelia with Multiple Malformations Syndrome is inherited in an X-linked recessive manner.The exact gene on the X chromosome that causes X-Linked Tetra-Amelia with Multiple Malformations Syndrome is not known at the present time.What are the Causes of X-Linked Tetra-Amelia with Multiple Malformations Syndrome? (Etiology) It is always important to discuss the effect of risk factors with your healthcare provider. Some risk factors are more important than others.Īlso, not having a risk factor does not mean that an individual will not get the condition. A risk factor increases one’s chances of getting a condition compared to an individual without the risk factors. It is important to note that having a risk factor does not mean that one will get the condition. Being a child of parents who are close blood relatives (such as first cousins) increases the risk of being born with X-Linked Tetra-Amelia with Multiple Malformations Syndrome.A positive family history may be an important risk factor, since X-Linked Tetra-Amelia with Multiple Malformations Syndrome can be inherited.What are the Risk Factors? (Predisposing factors) Worldwide, individuals of all racial and ethnic groups may be affected by this disorder. ![]()
