07 Jan 2025	Prepair 1000+ v1.992	PC	Ee Ming Wong changed review comment from: - Well-established gene disease association - Age of onset: neonatal to early childhood - Severity: variable severity - three subtypes 1. Type A (infantile form aka North American form): characterized by infantile onset of metabolic and lactic acidosis, delayed motor development, intellectual disability, poor linear growth and/or weight gain, and neurologic findings. Brain anomalies can be noted. Most affected children die in infancy or early childhood. 2. Type B (severe neonatal form aka French form): characterized by neonatal or infantile onset of hypothermia, respiratory distress/failure, vomiting, severe lactic acidosis, hyperammonemia, and often hypoglycemia. Neurologic findings include brain abnormalities, lethargy, hypotonia, and pyramidal and extrapyramidal signs. Death typically occurs by age eight months. 3. Type C (intermittent/attenuated form aka Benign form): characterized by relatively normal or mildly delayed neurologic development, motor and/or gait abnormalities, (rarely) seizures, episodic movement disorders, and metabolic acidosis. Life span is unknown but survival into adulthood has been reported.; to: - Well-established gene disease association - Age of onset: neonatal to early childhood - Severity: variable severity - three subtypes 1.

31 Oct 2024	Prepair 1000+ v1.525	SPG11	Lucy Spencer changed review comment from: OMIM: Charcot-Marie-Tooth disease type 2X (CMT2X) is an autosomal recessive, slowly progressive, axonal peripheral sensorimotor neuropathy characterized by lower limb muscle weakness and atrophy associated with distal sensory impairment and gait difficulties. Some patients also have involvement of the upper limbs. Onset usually occurs in the first 2 decades of life, although later onset can also occur (summary by Montecchiani et al., 2016). Mean age of onset 11.4 years. Hereditary spastic paraplegia (SPG or HSP) is characterized by progressive weakness and spasticity of the lower limbs due to degeneration of corticospinal axons. SPG11 is a form of complicated SPG, in that it has neurologic features in addition to spasticity. ClinGen lumps all 3 conditions under spastic paraplegia 11 Autosomal recessive juvenile amyotrophic lateral sclerosis-5 (ALS5) is a neurodegenerative disorder characterized by onset of upper and lower motor neuron signs before age 25. Affected individuals have progressive spasticity of limb and facial muscles associated with distal amyotrophy. The disorder is slowly progressive, with cases of prolonged survival of more than 3 decades (summary by Orlacchio et al., 2010).; to: OMIM: Charcot-Marie-Tooth disease type 2X (CMT2X) is an autosomal recessive, slowly progressive, axonal peripheral sensorimotor neuropathy characterized by lower limb muscle weakness and atrophy associated with distal sensory impairment and gait difficulties.

22 Mar 2024	Prepair 1000+ v1.5	ADPRHL2	Zornitza Stark changed review comment from: Fourteen unrelated families reported with stress-induced childhood-onset neurodegeneration with variable ataxia and seizures (CONDSIAS), an autosomal recessive neurodegenerative disorder with onset in the first years of life following normal early development. The disorder is characterised by cyclic episodic deterioration in response to stress, such as infection or febrile illness. The severity is highly variable: some individuals develop seizures early in life that are associated with loss of developmental milestones and early sudden death in childhood, whereas others present at a later age with muscle weakness, gait ataxia, impaired speech, more subtle clinical deterioration, and cognitive decline. Neurologic involvement includes gait ataxia, cerebellar signs associated with cerebellar atrophy, generalized brain atrophy, impaired intellectual development, hearing loss, and peripheral neuropathy. New HGNC approved name is ADPRS.; to: Fourteen unrelated families reported with stress-induced childhood-onset neurodegeneration with variable ataxia and seizures (CONDSIAS), an autosomal recessive neurodegenerative disorder with onset in the first years of life following normal early development.
