Cited in Scopus: 9With recent advances in DNA sequencing technology, it is now possible to begin to appreciate the full scope of DNA variation that arises over the course of an individual’s lifetime.1,2 Our understanding of how the human genome changes over time and in response to external exposures is growing with the improved availability of next-generation sequencing (NGS) based testing, including exome/genome sequencing of large patient cohorts. Clinical laboratories employing NGS-based methodologies can detect many types of DNA sequence variation including those that are present at a reduced variant allele fraction (VAF) (i.e., less than the 50% expected for a heterozygous germline finding). - ACMG StatementOpen Archive

Cited in Scopus: 6Mucopolysaccharidosis, type II (MPS II, MIM 309900) is a severe lysosomal storage disease with multisystem involvement. There is one product approved by the FDA, an enzyme replacement therapy, based on a phase III trial in older, attenuated MPS II individuals. Guidance on treatment of MPS II is lacking, not only in general, but for specific clinical situations. A previous systematic evidence-based review of treatment for MPS II demonstrated insufficient strength in all data analyzed to create a definitive practice guideline based solely on published evidence. - ACMG StatementOpen Archive

Cited in Scopus: 61In 1980, Eric Engel1 first proposed the concept of uniparental disomy (UPD), in which both homologous chromosomes are inherited from one parent, with no contribution (for that chromosome) from the other parent. In 1988, the first case of a Mendelian disorder associated with UPD was reported, in which a child with cystic fibrosis (MIM 219700) had inherited two copies of a pathogenic variant in CFTR (MIM 602421) from a heterozygous carrier mother, with no contribution from the biological father.2 - ACMG StatementOpen Archive
Points to consider for reporting of germline variation in patients undergoing tumor testing: a statement of the American College of Medical Genetics and Genomics (ACMG)

Cited in Scopus: 43The sequencing of tumor-derived DNA to identify tumor-specific variations (biomarkers) with potential diagnostic, prognostic, or predictive therapeutic implications (hereafter, “tumor testing”) is a prominent example of precision medicine. Although the primary goal of this testing is the identification of biomarkers to guide patient management, testing tumor genomes also has the potential to uncover clinically relevant germline variation that is associated with heritable cancer susceptibility and other conditions, and carrier status for autosomal recessive disorders, if confirmed to be present in the germline. - ACMG StatementOpen Archive

Cited in Scopus: 0This document represents an update to the proposed approach of the American College of Medical Genetics and Genomics (ACMG) to categorize laboratory-developed tests (LDTs) for inherited conditions according to risk.1 Risk classification has historically been a determinant of whether, and to what extent, the US Food and Drug Administration (FDA) has overseen and regulated clinical tests. LDTs for constitutional variants continue to proliferate without a comprehensive federal regulatory framework in place. - ACMG Systematic Evidence ReviewOpen Archive

Cited in Scopus: 11Peroxisomal disorders are a clinically and genetically heterogeneous group of diseases caused by defects in peroxisomal biogenesis or function, usually impairing several metabolic pathways. Peroxisomal disorders are rare; however, the incidence may be underestimated due to the broad spectrum of clinical presentations. The inclusion of X-linked adrenoleukodystrophy to the Recommended Uniform Screening Panel for newborn screening programs in the United States may increase detection of this and other peroxisomal disorders. - ACMG StatementOpen Archive

Cited in Scopus: 104Approximately 2–4% of pregnancies are complicated by significant fetal structural anomalies. Given respect for reproductive autonomy, all patients diagnosed with a fetal anomaly should be offered genetic counseling, including review of options for genetic testing.1 The prenatal testing strategy and test selection should be individualized and guided by prenatal imaging findings and family history. Current options include chromosomal studies by karyotyping, fluorescence in situ hybridization, and chromosomal microarray analysis (CMA) with consideration of targeted gene-specific molecular testing for suspected disorders. - ACMG Technical StandardsOpen Archive

Cited in Scopus: 58Gene sequencing panels are a powerful diagnostic tool for many clinical presentations associated with genetic disorders. Advances in DNA sequencing technology have made gene panels more economical, flexible, and efficient. Because the genes included on gene panels vary widely between laboratories in gene content (e.g., number, reason for inclusion, evidence level for gene–disease association) and technical completeness (e.g., depth of coverage), standards that address technical and clinical aspects of gene panels are needed. - ACMG Technical StandardsOpen Archive
Laboratory screening and diagnosis of open neural tube defects, 2019 revision: a technical standard of the American College of Medical Genetics and Genomics (ACMG)

Cited in Scopus: 12Open 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.
