Use of genetic counselling services for neural tube defects
Insights
Genetic counselling is recommended for parents of children with neural tube defects (NTDs). Service use varies by NTD type and birth outcome, with spina bifida births most frequently seeking counselling.
Area of Science:
- Medical Genetics
- Public Health
- Reproductive Medicine
Background:
- Genetic counselling is crucial for parents of children diagnosed with neural tube defects (NTDs).
- It provides essential information on recurrence risks and prenatal diagnostic options.
- British Columbia offers a unique setting for studying genetic counselling utilization due to centralized services and complete ascertainment of NTD births.
Purpose of the Study:
- To examine the utilization patterns of genetic counselling services for neural tube defects (NTDs) in British Columbia.
- To identify factors influencing parental decisions to seek genetic counselling following an NTD diagnosis.
Main Methods:
- Analysis of genetic counselling service utilization data for neural tube defect (NTD) cases in British Columbia.
- Correlation of service use with NTD type and infant outcome (liveborn vs. stillborn).
Main Results:
- Utilization of genetic counselling services is significantly influenced by the specific type of neural tube defect (NTD).
- The outcome of the index case (liveborn or stillborn) also affects the uptake of genetic counselling.
- Genetic counselling is most commonly sought after the birth of a liveborn infant diagnosed with spina bifida.
Conclusions:
- Parental decisions regarding genetic counselling for NTDs are complex and multifactorial.
- Targeted information and support may be beneficial, particularly for specific NTD types and outcomes.
- Understanding these patterns can help optimize genetic service delivery for affected families.
Abstract:
Genetic counselling is recommended for parents of children with neural tube defects (NTDs) to inform them of the recurrence risks and the option of prenatal diagnosis. British Columbia provides an excellent site to examine the use by parents of genetic counselling services for NTDs. Genetic services for the entire province are centralized, and there is virtually complete ascertainment of all NTD births. The results from this study indicate that use of genetic counselling services is influenced by the type of NTD present and whether the index case was live or stillborn. Genetic counselling is most often sought after the birth of a liveborn infant with spina bifida.
