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

American 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

American 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.

Distinct Neuropsychiatric Profiles Associated With 17p11.2 Deletions and RAI1 Variants in Smith–Magenis Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Smith–Magenis syndrome (SMS) results from either a recurrent 17p11.2 deletion or pathogenic variants in the retinoic acid induced 1 gene (RAI1). While neurodevelopmental impairment and behavioral dysregulation are well recognized, systematic genotype‐stratified analyses across psychiatric domains remain limited.

Sleep Disturbances in Adults With Tuberous Sclerosis Complex: Influences of Treatment and Clinical Features

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Tuberous sclerosis complex (TSC) is a genetic condition with multisystem neurocutaneous signs, including hamartomas, epilepsy, and neuropsychological difficulties. Although sleep disorders are increasingly recognized in TSC, they remain poorly described in adults.

Refining Domain‐Based Prognostication in DNM1 Encephalopathy: A Mild Phenotype Associated With a GTPase Domain Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT DNM1 encephalopathy is a rare autosomal dominant genetic condition characterized by a range of neurological and developmental manifestations. The typical phenotype is severe, including profound intellectual disability, treatment‐resistant epilepsy, ataxia, and structural brain abnormalities. However, milder presentations have increasingly been

Cerebellar Abnormalities in the Neuroimaging Spectrum of CLTC‐Related Disorder

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Pathogenic variants in CLTC, which encodes the clathrin heavy chain involved in vesicle‐mediated trafficking in neurons, cause a rare neurodevelopmental disorder associated with variable severity of global developmental delay and intellectual disability and structural brain abnormalities. Although corpus callosum and white matter anomalies are
