Optic Atrophy Secondary to Ophthalmic Artery Aneurysm

, 2023
Optic neuropathy caused by an aneurysm is rare, with an incidence of 1.4% among patients with an aneurysm. Aneurysms typically rupture before becoming large enough to compress the sensory visual pathways.

dominant optic atrophy phenotype: Infantile nystagmus and optic atrophy without spastic paraplegia

, 2023
Spastic paraplegia is a neurodegenerative disorder characterized by progressive leg weakness and spasticity due to degeneration of corticospinal axons. SPG7 encodes paraplegin, and pathogenic variants in the gene cause hereditary spastic paraplegia as an

PUS7 Deficiency: Phenotypical Expansion of PUS7‐Related Neurodevelopmental Disorders

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Pathogenic variants in PUS7, encoding pseudouridine synthase 7, cause a rare neurodevelopmental disorder marked by intellectual disability, microcephaly, short stature, and behavioral disturbances. Since the first report in 2018, only 16 patients have been described.

Severe ADEM‐Like Neuroinflammatory Disease and Cerebrovascular Fragility With Recurrent Pseudoaneurysms and Moyamoya in a Familial Germline CBL Mutation: Expanding the Clinical Phenotype

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous germline variants in CBL disrupt its function as a negative regulator of the Ras/MAPK pathway, classically predisposing to Juvenile myelomonocytic leukemia (JMML) and moyamoya. We describe two affected siblings carrying a paternally inherited CBL variant (c.1210 T> C, p.

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

A Rare Form of Microcephalic Primordial Dwarfism due to NSMCE2 Deficiency (Seckel Syndrome Type 10): A Report of Macular Involvement

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic variants in NSMCE2 (MMS21), which encodes the SUMO E3 ligase subunit of the SMC5/6 chromatin‐maintenance complex, have recently been implicated in microcephalic primordial dwarfism (MPD), corresponding to Seckel syndrome type 10 (OMIM #617246).

ADNP‐Related Helsmoortel–Van der Aa Syndrome: A Review of the Literature and Clinical Recommendations for Assessment and Monitoring

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT ADNP‐related Helsmoortel–Van der Aa syndrome (ADNP‐related HVDAS) is a single gene form of autism spectrum disorder (ASD) caused by pathogenic sequence variants in the activity‐dependent neuroprotective protein (ADNP) gene. In addition to ASD, ADNP‐related HVDAS is associated with a wide range of cognitive, behavioral, and physical health ...

L‐Cysteine and N‐Acetylcysteine Supplementation Improves Clinical Outcome in a Patient With COXPD10

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT MTO1 is a nuclear gene that encodes a mitochondrial protein essential for modifying mitochondrial transfer RNAs (tRNAs) and stabilizing codon‐anticodon interactions to ensure accurate and efficient mitochondrial protein synthesis and oxidative phosphorylation.
