What Does NxGen MDx Screen For?
We screen for up to 120 genetic disorders that can affect your pregnancy, the health of your baby, and your family's future. You can learn more about our various screens — and which sets of screens (or "panels") align with where you are in your reproductive journey.
Congenital Amegakaryocytic Thrombocytopenia
What Your Test Results Mean:
Carriers are not expected to show symptoms. You and your partner or donor would both have to be carriers of CAMT for there to be an increased chance to have a child with symptoms; this is known as autosomal recessive inheritance. Carrier testing of your partner or donor is recommended in addition to consultation with a genetic counselor for a more detailed risk assessment.
Since this is an inherited gene change, this information may be helpful to share with family members as it may impact their family planning.
Congenital amegakaryocytic thrombocytopenia (CAMT) is an inherited condition that causes bone marrow failure. Symptoms of CAMT first begin to show during infancy, often during the first month of life. CAMT is characterized by excessive, life-threatening bleeding, bruising, and tiny red dots under the skin that result from small bleeds into the skin known as petechiae. Affected individuals may also experience central nervous abnormalities, cardiac defects, and psychomotor delays.
With supportive treatment, bone marrow failure occurs around the first decade of life. Hematopoietic stem cell transplant (HSCT) is considered curative and is successful for over 50% of affected individuals. Thirty percent of patients with CAMT die from bleeding complications before the HSCT and 20% due to the HSCT.
Treatment for CAMT may include bone marrow or hematopoietic stem cell transplant. Affected individuals may also benefit from blood transfusions.
