- Partial trisomy involves the presence of part of an extra copy of chromosome 13 in the cells.
- Trisomy 13 mosaicism occurs when some of the cells have an extra chromosome 13.
- Trisomy 13 has a full extra copy of chromosome 13 in all of the cells.
Each child with Trisomy 13 will have different needs depending on what symptoms are evident. Some common issues include:
- Cleft lip or palate
- Close set eyes - may even fuse into one structure
- Extra fingers or toes
- Limb abnormalities
- Small head
- Small lower jaw
- Congenital heart defects - placement toward right side of chest, septal or ductal defects
- Holoprosencephaly - the forebrain doesn't divide properly
Caring for an infant with Trisomy 13 often involves addressing breathing issues like apnea, feeding problems, heart failure, seizures, and challenges with seeing and hearing. It is essential for families to find support as they walk through caring for a child with Trisomy 13. One well-known organization to contact is SOFT. Another is Hope for Trisomy 13 and 18.
How fitting that March is Trisomy Awareness month!
