ACOG has released two committee opinions on carrier screening. Committee Opinion 691 reviews the recommendations based on disorders. Committee Opinion 690 addresses the issues related to use of screening strategies such as expanded gene panel testing.
Changes to look for compared to previous guidance include the following:
Spinal Muscular Atrophy (SMA) has now joined cystic fibrosis (CF) as a recommendation for all women who are pregnant or considering pregnancy
Test all patients for CBC and RBC indices as part of antepartum care (ideally preconception)
Add Hgb electrophoresis if:
Increased risk based on ethnicity: African, Middle Eastern, Southeast Asian, West Indian and Mediterranean ancestry
MCV is less than 80 fL with normal iron studies
Ashkenazi Jewish Testing (central and Eastern Europe descent)
Additional tests to ‘consider’ has been expanded to the following
Usher syndrome, Familial hyperinsulinism, Joubert and Maple syrup urine disease in addition to Bloom/Gaucher/Fanconi anemia/ML4/Neimann-Pick disease
Tay Sachs Disease
In addition to Ashkenazi Jews, offer if either partner is French-Canadian descent or Cajun
Screening can be performed using DNA-based testing (mutation analysis) or hexosaminidase enzyme in serum or leuckocytes (leukocyte only with oral contraceptives)
Enzyme testing picks up approximately 98% of carriers regardless of ethnicity
Mutation analysis is highly effective in at risk populations – detection rate is limited in other populations
Committee Opinion 690 reviews expanded carrier screening, including a discussion on counseling and what disorders should be included | Important summary statements include the following:
Ethnic-specific, panethnic, and expanded carrier screening are acceptable strategies for prepregnancy and prenatal carrier screening. Each obstetrician–gynecologist or other health care provider or practice should establish a standard approach that is consistently offered to and discussed with each patient, ideally before pregnancy. After counseling, a patient may decline any or all carrier screening.
Expanded carrier screening does not replace previous risk-based screening recommendations. If obstetrician–gynecologists or other health care providers do not offer expanded carrier screening in their practice, screening recommendations for individual disorders should follow guidelines for carrier screening as outlined in Committee Opinion No. 691, Carrier Screening for Genetic Conditions.
Note: ACMG has published a document on preconception and prenatal carrier screening that includes a tiered approach to the selection of disorders | For the summary and links see ‘Related ObG Topics’ below)
