An individual with triploidy has 69 chromosomes. This is a rare chromosomal abnormality where a fetus has three copies of every chromosome instead of the usual two, for a total of 69 chromosomes instead of 46. Triploidy is a life-threatening condition that often leads to miscarriage or stillbirth. In rare cases, babies with triploidy may survive for a short period after birth.
Causes of Triploidy:
- Fertilization of an egg by two sperm: This is the most common cause of triploidy, resulting in an extra set of chromosomes.
- Problems with cell division during early embryonic development: This can also lead to triploidy.
Symptoms of Triploidy:
- Growth retardation: The fetus may be smaller than expected.
- Heart defects: These are common in babies with triploidy.
- Brain abnormalities: These can also be present.
- Facial abnormalities: These are common in babies with triploidy.
- Cleft palate: This is a common finding in babies with triploidy.
Diagnosis of Triploidy:
- Prenatal ultrasound: This can be used to detect triploidy.
- Chorionic villus sampling (CVS): This is a prenatal test that can be used to diagnose triploidy.
- Amniocentesis: This is a prenatal test that can be used to diagnose triploidy.
Treatment of Triploidy:
There is no cure for triploidy. Treatment focuses on managing symptoms and providing supportive care.
