Expanding the Phenotype of TUFM‐Related Combined Oxidative Phosphorylation Deficiency 4

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Combined oxidative phosphorylation deficiency 4 (COXPD4) is a rare mitochondrial condition caused by biallelic deleterious variants in the nuclear‐encoded gene TUFM. To date, most individuals with COXPD4 have presented with encephalopathy, hypotonia, and abnormal brain imaging. Many of the reported individuals died in infancy. We aim to expand

Phenotype Expansion of Malan Syndrome: New Cases and a Review of the Literature

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Malan syndrome is an ultra‐rare overgrowth syndrome caused by pathogenic variants or deletions in nuclear factor one X (NFIX) located at 19p13.2. Here, we report a comprehensive literature review and phenotyping of known patients with Malan syndrome and present a novel cohort of eight patients.

De Novo 2.2 Mb 19q13.42–q13.43 Microdeletion Encompassing U2AF2: Support for a Haploinsufficiency Model

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT U2 small nuclear RNA auxiliary factor 2 (U2AF2) is an essential pre‐mRNA splicing factor involved in the early stages of pre‐mRNA splicing. To date, multiple individuals have been reported with predominantly heterozygous missense variants presenting intellectual disability, speech and motor delays, seizures, hypotonia, and thin or hypoplastic ...

Histidine Supplementation Stabilizes Hearing and Vision and Improves Growth in HARS1‐Related Autosomal Recessive Disorder Associated With Usher‐Like Symptoms

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autosomal recessive HARS1‐related disorder (originally described as Usher syndrome type 3B) caused by a homozygous Y454S variant in the histidyl‐tRNA synthetase gene (HARS1) is characterized by progressive sensorineural hearing and vision loss and respiratory deterioration with risk for sudden death following febrile illnesses.

A Novel Splice Variant in ERGIC1 Causes Arthrogryposis Multiplex Congenita—Characterization Using Urine‐Derived Cells

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Arthrogryposis multiplex congenita (AMC) is defined as the presence of joint contractures affecting at least two body regions at birth. Three different ERGIC1 variants have been reported in individuals with AMC. Here, we report on a 16‐year‐old male with a homozygous ERGIC1 c.250+1G>A variant that was classified as a variant of uncertain ...

Establishment of a chronic aspiration pneumonia mouse model using oropharyngeal aspiration of food suspension

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Four aspiration methods (UV, IN, IT, and OA) were compared, and OA was identified as the most effective delivery technique. A chronic aspiration pneumonia model was then established through repeated OA of food suspension or gastric contents. Integrated analyses, including micro‐CT, histopathology, cytokine profiling, and RNA sequencing, revealed ...
