501 Possible Causes for Axial Hypotonia

  • Aromatic L-Amino Acid Decarboxylase Deficiency

    Characteristic features included axial hypotonia, hypokinesia, and athetosis, with superimposed episodes of ocular convergence spasm, oculogyric crises, dystonia, and limb[] The presentation of symptoms is variable and there are variable degrees of severity Neonatal Period Feeding difficulties Autonomic dysfunction Hypotonia Motor symptoms Axial[] hypotonia (decreased tone or floppy - trunk, head and limbs) Limb hypertonia (increased tone to the limbs) Fluctuating limb tone Hypokinesia (decreased spontaneous movements[]

  • Hypomyelinating Leukodystrophy Type 5

    In severe cases, children fail to achieve motor milestones and linguistic development, and show profound axial hypotonia.[] These infants show axial hypotonia with difficult head control, titubation, exaggerated tendon reflexes, and a combination of ataxia and extrapyramidal features.[]

  • Warburg Micro Syndrome 3

    hypotonia, hypotonic upper limbs, hypertonic lower limbs with contractures, myoclonic seizures, and hypoplastic labia minora and clitoral hypoplasia.[] The clinical picture evolved to a spastic tetraparesis with axial hypotonia and limbs dystonic movement disorder. He had dysphagia and severe intellectual disability.[] Additional systemic manifestations included axial hypotonia with evolving limb spasticity, and occasional seizures.[]

  • Amish Lethal Microcephaly

  • Propionic Acidemia

    Neurological examination revealed axial hypotonia, severe spastic tetraparesis and extrapyramidal syndrome with numerous opisthotonos episodes daily.[]

  • Congenital Hypothyroidism without Goiter

    In two generations its presence was detected in the hemizygous state in two males with neurological abnormalities including mental retardation, axial hypotonia, hypertonia[] This syndrome is characterized by axial hypotonia, severe mental retardation, dysarthria, athetoid movements, spastic paraplegia, and a typical thyroid hormone profile.[] He presents mental retardation, axial hypotonia, hypertonia of arms and legs, paroxysmal dyskinesias, seizures.[]

  • Cerebro-Oculo-Facio-Skeletal Syndrome Type 1

    They also exhibit a predominantly postnatal growth failure, a severe psychomotor retardation, with axial hypotonia and peripheral hypertonia and neonatal feeding difficulties[]

  • Histiocytoid Cardiomyopathy

    At birth, clinical examination revealed a systolic cardiac murmur, an axial hypotonia, linear cutaneous erythematous lesions of the face and the neck typical of the microphthalmia[]
