Anesthetic Management of a Patient With S-Adenosylhomocysteine Hydrolase Deficiency: A Case Report.

S-adenosylhomocysteine hydrolase (AHCY) deficiency is a rare congenital disorder in methionine metabolism with minimal guidelines regarding anesthetic management. This case report describes a 19-year-old man presenting for a liver biopsy in interventional radiology due to a history of elevated aminotransferases and creatine kinase. He received dextrose-containing fluids and a total intravenous anesthetic to avoid rhabdomyolysis and hyperkalemia.

Craniofacial features of 3q29 deletion syndrome: Application of next-generation phenotyping technology.

3q29 deletion syndrome (3q29del) is a recurrent deletion syndrome associated with neuropsychiatric disorders and congenital anomalies. Dysmorphic facial features have been described but not systematically characterized. This study aims to detail the 3q29del craniofacial phenotype and use a machine learning approach to categorize individuals with 3q29del through analysis of 2D photos.

Functional interpretation of ATAD3A variants in neuro-mitochondrial phenotypes.

Background: ATPase family AAA-domain containing protein 3A (ATAD3A) is a nuclear-encoded mitochondrial membrane-anchored protein involved in diverse processes including mitochondrial dynamics, mitochondrial DNA organization, and cholesterol metabolism. Biallelic deletions (null), recessive missense variants (hypomorph), and heterozygous missense variants or duplications (antimorph) in ATAD3A lead to neurological syndromes in humans.

Methods: To expand the mutational spectrum of ATAD3A variants and to provide functional interpretation of missense alleles in trans to deletion alleles, we performed exome sequencing for identification of single nucleotide variants (SNVs) and copy number variants (CNVs) in ATAD3A in individuals with neurological and mitochondrial phenotypes.

Heterogeneous Pulmonary Phenotypes in Filamin A Mutation-Related Lung Disease.

Interstitial lung disease (ILD) has been recently reported in a few patients with pathogenic variants in the Filamin A () gene with variable presentation and prognosis. This study evaluated the respiratory manifestations and clinical features in children with disease. We conducted a retrospective review of pediatric patients with variants in in a tertiary children's hospital.

Two Angelman families with unusually advanced neurodevelopment carry a start codon variant in the most highly expressed UBE3A isoform.

We present three children from two unrelated families with Angelman syndrome (AS) whose developmental skills are far more advanced than any other non-mosaic AS individual ever reported. All have normal gait and use syntactic language spontaneously to express their needs. All of them have a c.
