Insights
This case study details a 4-year-old girl with complete tetraploidy, a rare condition typically associated with a limited lifespan. Her survival and development offer unique insights into managing this complex genetic disorder.
Area of Science:
- Genetics
- Pediatrics
- Developmental Biology
Background:
- Complete tetraploidy is a rare chromosomal abnormality.
- Infants with complete tetraploidy usually have a limited lifespan due to severe complications.
Abstract:
We present the case of a girl with complete tetraploidy who has survived to her present age of 4 years and 1 month. Infants with complete tetraploidy have been described to have a limited lifespan owing to complications. We report her characteristics, medical history, and development.
