    Abstract Biallelic intronic repeat expansion in the RFC1 gene was reported as a cause of cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS). Its clinical features include late-onset cerebellar ataxia, sensory neuropathy (or neuronopathy), bilateral vestibular impairment, autonomic dysfunction, chronic cough, pyramidal sign, or parkinsonism. Repeat conformations heterogeneity is observed along with the possible phenotype-genotype correlation while its molecular pathogenesis remains uncovered.

    Abstract Neuronal intranuclear inclusion disease (NIID) is a rare, progressive neurodegenerative disorder known for its diverse clinical manifestations. Although episodic neurogenic events can be associated with NIID, no reported cases have demonstrated concurrent clinical features or MRI findings resembling reversible cerebral vasoconstriction syndrome (RCVS). Here, we present the inaugural case of an adult-onset NIID patient who initially displayed symptoms reminiscent of RCVS. The 59-year-old male patient's initial presentation included a thunderclap headache, right visual field deficit, and confusion. Although his brain MRI appeared normal, MR angiography unveiled left posterior cerebral artery occlusion, subsequently followed by recanalization, culminating in an RCVS diagnosis. Over an 11-year period, the patient encountered 10 additional episodes, each escalating in duration and intensity, accompanied by seizures. Simultaneously, cognitive impairment progressed. Genetic testing for NIID revealed an abnormal expansion of GGC repeats in

    Abstract We herein report a case with a novel homozygous variant in the kyphoscoliosis peptidase (KY) gene. A 58-year-old Japanese female was referred to our hospital with a gait disturbance that gradually worsened after the age of 50. She had bilateral equinus foot deformity since early childhood. Neurological examination revealed moderate weakness of the neck, trunk, femoral, and brachial muscles, mild respiratory failure, and areflexia. Whole-exome sequencing revealed a novel homozygous frameshift variant of the KY gene, NM_178554.6:c.824del p.(Glu275Glyfs*53). Our case demonstrated that KY-associated neuromuscular disease can present with extremely slow progressive muscle weakness and respiratory failure over a long natural course.

    Abstract Introduction: CAD (MIM*114010) encodes a large multifunctional protein with the enzymatic activity of the first three enzymes initiating and controlling the de novo pyrimidine biosynthesis pathway. Biallelic pathogenic variants in CAD cause the autosomal recessive developmental and epileptic encephalopathy 50 (MIM #616457) or CAD deficiency presenting with epilepsy, status epilepticus (SE), neurological deterioration and anemia with anisopoikilocytosis. Mortality is around 9% of patients, mainly related to the no use of its specific treatment with uridine. Majority of reported cases have an early onset during infancy, with some few starting later in childhood.
    Case report: Here we report a deceased female patient with CAD deficiency whose epilepsy started at 14 years. She showed a rapid neurologic deterioration including cognitive decline, electroencephalographic background slowing which later evolved to a fatal refractory SE and supra and infratentorial atrophy on neuroimaging. Anemia developed after SE onset.
    Methods and results: her post-mortem whole exome sequencing identified biallelic missense variants in CAD (NM_004341.5): c.[2944G > A];[5366G > A] p.[(Asp982Asn)];[(Arg1789Gln)]. Our review of twenty-eight reported cases (2015-2023) revealed an epilepsy age onset from neonatal period to 7 years and the SE prevalence of 46 %.
    Discussion: With our case, we highlight the relevance of suspecting this treatable condition in older patients and in SE with no evident etiology.
