Artificial intelligence enables comprehensive genome interpretation and nomination of candidate diagnoses for rare genetic diseases

Genome Med. 2021 Oct 14;13(1):153. doi: 10.1186/s13073-021-00965-0. ABSTRACT BACKGROUND: Clinical interpretation of genetic variants in the context of the patient’s phenotype is becoming the largest component of cost and time expenditure for genome-based diagnosis of rare genetic diseases. Artificial intelligence (AI) holds promise to greatly simplify and speed genome interpretation by integrating predictive methods with […]

Insights into the expanding phenotypic spectrum of inherited disorders of biogenic amines

Nat Commun. 2021 Sep 20;12(1):5529. doi: 10.1038/s41467-021-25515-5. ABSTRACT Inherited disorders of neurotransmitter metabolism are rare neurodevelopmental diseases presenting with movement disorders and global developmental delay. This study presents the results of the first standardized deep phenotyping approach and describes the clinical and biochemical presentation at disease onset as well as diagnostic approaches of 275 patients […]

Maternal Smoking and Congenital Heart Defects, National Birth Defects Prevention Study, 1997-2011

J Pediatr. 2021 Sep 8:S0022-3476(21)00877-5. doi: 10.1016/j.jpeds.2021.09.005. Online ahead of print. ABSTRACT OBJECTIVES: To assess associations between maternal smoking and congenital heart defects (CHDs) in offspring. STUDY DESIGN: We performed a retrospective case-control study using data for cases of CHD (n=8,339) and non-malformed controls (n=11,020) children from all years (1997-2011) of the National Birth Defects […]

To Be or No B2: A Rare Cause of Stridor and Weakness in a Toddler

Child Neurol Open. 2021 Aug 5;8:2329048X211030723. doi: 10.1177/2329048X211030723. eCollection 2021 Jan-Dec. ABSTRACT We present a case of a young child with a rare metabolic disorder whose clinical presentation resembled that of autoimmune myasthenia gravis. The differential diagnosis was expanded when autoantibody testing was negative and the patient did not respond to standard immunomodulatory therapies. Rapid […]

Use of Metagenomic Next-Generation Sequencing to Identify Pathogens in Pediatric Osteoarticular Infections

Open Forum Infect Dis. 2021 Jul 17;8(7):ofab346. doi: 10.1093/ofid/ofab346. eCollection 2021 Jul. ABSTRACT BACKGROUND: Osteoarticular infections (OAIs) are frequently encountered in children. Treatment may be guided by isolation of a pathogen; however, operative cultures are often negative. Metagenomic next-generation sequencing (mNGS) allows for broad and sensitive pathogen detection that is culture-independent. We sought to evaluate […]

Ending a diagnostic odyssey: Moving from exome to genome to identify cockayne syndrome

Mol Genet Genomic Med. 2021 Jun 2:e1623. doi: 10.1002/mgg3.1623. Online ahead of print. ABSTRACT BACKGROUND: Cockayne syndrome (CS) is a rare autosomal recessive disorder characterized by growth failure and multisystemic degeneration. Excision repair cross-complementation group 6 (ERCC6 OMIM: *609413) is the gene most frequently mutated in CS. METHODS: A child with pre and postnatal growth […]

Failure to thrive – an overlooked manifestation of KMT2B-related dystonia: a case presentation

BMC Neurol. 2020 Jun 16;20(1):246. doi: 10.1186/s12883-020-01798-x. ABSTRACT BACKGROUND: KMT2B-related dystonia is a recently described form of childhood onset dystonia that may improve with deep brain stimulation. Prior reports have focused on neurologic features including prominent bulbar involvement without detailing general health consequences that may result from orolingual dysfunction. We describe a family with novel […]

The Medical Genome Initiative: moving whole-genome sequencing for rare disease diagnosis to the clinic

Genome Med. 2020 May 27;12(1):48. doi: 10.1186/s13073-020-00748-z. ABSTRACT Clinical whole-genome sequencing (WGS) offers clear diagnostic benefits for patients with rare disease. However, there are barriers to its widespread adoption, including a lack of standards for clinical practice. The Medical Genome Initiative consortium was formed to provide practical guidance and support the development of standards for […]
