ACMG Statements and Guidelines
These online statements and guidelines are definitive and may be cited using the digital object identifier (DOI). These recommendations are designed primarily as an educational resource for medical geneticists and other healthcare providers to help them provide quality medical genetics services; they should not be considered inclusive of all proper procedures and tests or exclusive of other procedures and tests that are reasonably directed to obtaining the same results.

Noninvasive prenatal screening (NIPS) for fetal chromosome abnormalities in a general-risk population: An evidence-based clinical guideline of the American College of Medical Genetics and Genomics (ACMG)
This workgroup aimed to develop an evidence-based clinical practice guideline for the use of noninvasive prenatal screening (NIPS) for pregnant individuals at general risk for fetal trisomy 21, trisomy 18, or trisomy 13 and to evaluate the utility of NIPS for other chromosomal disorders.Stewardship of patient genomic data: A policy statement of the American College of Medical Genetics and Genomics (ACMG)
Human genomic data linked to health records have become valuable in the quest to establish correlations between disease and genetic information. As a result, it has become increasingly common for patient genetic information obtained through clinical testing or other means to be de-identified and linked to health records for sale or transfer to a third party for research and development purposes (eg, novel drug targets, patient and provider tools for managing health care). Unlike many other elements within the de-identified data set, however, the patient’s genetic information in various forms (eg, DNA sequence, RNA sequence, aggregated variant data, optical mapping) may be sufficiently information-rich to permit reidentification of the patient using informatics tools in some cases and is considered by some to be inherently identifiable.Laboratory screening and diagnosis of open neural tube defects, 2019 revision: a technical standard of the American College of Medical Genetics and Genomics (ACMG)
Open neural tube defects (ONTDs) include open spina bifida (OSB) and anencephaly. These defects are caused by incomplete closure of the neural tube at about 4 weeks of pregnancy. Levels of early second-trimester maternal serum (ms) alpha-fetoprotein (AFP) are sufficiently elevated in affected pregnancies to be used as a population-based screening test. The basic screening methodology was described in the late 1970s and screening programs were active a few years later. By identifying pregnancies with the highest msAFP levels, about 80% of OSB and 95% of anencephaly can be identified as early as 16 weeks gestation.Patient re-contact after revision of genomic test results: points to consider—a statement of the American College of Medical Genetics and Genomics (ACMG)
Nearly two decades ago, the American College of Medical Genetics (now the American College of Medical Genetics and Genomics [ACMG]) Policy Statement “Duty to re-contact” was prescient in highlighting the increasingly important issue of patient re-contact.1 Originally focused on clinical genetics practice, its importance now extends to both medical genomics and medical practice in general. Next-generation genomic testing, including multigene panels, exome sequencing (ES), and genome sequencing (GS), is permitting ever larger amounts of data to be collected on each patient sample, with a corresponding increase in the complexity of the results.Noninvasive prenatal screening for fetal aneuploidy, 2016 update: a position statement of the American College of Medical Genetics and Genomics
Disclaimer: This statement is designed primarily as an educational resource for clinicians to help them provide quality medical services. Adherence to this statement is completely voluntary and does not necessarily assure a successful medical outcome. This statement should not be considered inclusive of all proper procedures and tests or exclusive of other procedures and tests that are reasonably directed toward obtaining the same results. In determining the propriety of any specific procedure or test, the clinician should apply his or her own professional judgment to the specific clinical circumstances presented by the individual patient or specimen.
