THE PRENATAL AND REPRODUCTIVE GENETICS CLINIC @ SGH O&G
The Prenatal and Reproductive Genetics Clinic is a weekly clinic at the Singapore General Hospital Obstetrics & Gynaecology Centre. It is run jointly by a maternal-foetal medicine specialist with training in perinatal genetics, as well as a senior genetic counsellor.
This collaborative set-up expedites and improves care by giving patients the opportunity to receive counselling from both an obstetric as well as a genetic counselling perspective in one session.
OUR SERVICES AND WHO GPs CAN REFER
We welcome referrals for the following groups of pregnant patients and those preparing for pregnancy:
1.
| Previously affected pregnancy or child | Patients at higher risk of having a pregnancy affected by a genetic condition include those with a past history of an affected child, or a personal or family history of a genetic condition, intellectual disability or birth defect. They may be referred for discussion on recurrence risk and options for further testing. |
2. | Consanguinity |
3.
| Family or personal history of genetic disorder or birth defect |
4. | Preimplantation genetic testing (PGT) | Patients at risk of having a child with certain genetic conditions may be eligible for PGT. They may be referred for counselling to understand the risk of an affected child and the PGT process. |
5.
| Pre-pregnancy carrier screening | Carrier screening is a valuable tool in family planning as it allows patients to determine if they carry genetic mutations that can increase the risk of having a child with an autosomal recessive or X-linked genetic condition. It is common to be a carrier for at least one condition, and most carriers are healthy with no personal or family history. As an example, the carrier frequency for spinal muscular atrophy in the general population is estimated to be between 1 out of 40 to 60. The results from the carrier screening will enable patients at risk to explore their reproductive options and make informed decisions on prenatal or infant diagnostic testing. |
6.
| Screening for chromosomal conditions during pregnancy | There are various options for screening and diagnostic testing during pregnancy to determine the risk of a pregnancy being affected by chromosomal and genetic conditions. These include first trimester screening, cell-free DNA screening, ultrasound scans and invasive testing. Genetic counselling allows the couple to select a testing strategy that best aligns with their concerns and desired outcomes. |
7.
| Abnormal screening or diagnostic testing results | Patients with abnormal screening, diagnostic testing or ultrasound results may be referred for us to explain the findings and discuss the options for further testing, such as chorionic villus sampling and amniocentesis. |
8.
| Abnormal ultrasound findings |
