932 Possible Causes for Muscle Hypotonia, Speech Delay

  • 22q11.2 Duplication Syndrome

    The degree of developmental delay varied from mild global developmental delay to isolated speech delay or normal cognition.[] […] tone (hypotonia).[] Affected individuals may have intellectual or learning disability, developmental delay, slow growth leading to short stature, and weak muscle tone (hypotonia).[]

  • Angelman Syndrome

    He has mild developmental delay, moderate speech delay, and no seizures.[] Cerebellar ataxia, muscle hypotonia and tremor, though constant in childhood, tend to be attenuated in adulthood.[] HYPOTONIA ; and a peculiar facies.[]

  • Dubowitz Syndrome

  • Aspartylglucosaminuria

    The classical aspartylglucosaminuria phenotype (progressive speech delay, psychomotor retardation, and behavioral abnormalities) was observed in 3 Turkish siblings.[] Additional musculoskeletal (thickening of the ribs and skull, lordosis, vertebral dysplasia, contractures in fingers and elbows, a knock knee, muscle atrophy and hypotonia[] Initial symptoms may present as clumsiness and/or speech delay. Individuals with AGU also show increased upper respiratory infections.[]

  • Monosomy 1p36 Syndrome

    […] of speech development Delayed language development Delayed speech Delayed speech acquisition Delayed speech development Impaired speech and language development Impaired[] Affected individuals usually have weak muscle tone (hypotonia) and swallowing difficulties (dysphagia).[] Hypotonia may also delay sitting, crawling and walking. Muscle tone often improves with age and with physical therapy.[]

  • Macrocephaly-Developmental Delay Syndrome

    A child with speech delay has speech development that is typical of a normally developing child of a younger chronologic age; the speech-delayed child's skills are acquired[] However, young AS patients may also exhibit feeding difficulties and muscle hypotonia.[] Cohen Syndrome Malformations of the head and facial (craniofacial) area, eye (ocular) abnormalities, diminished muscle tone (hypotonia), obesity, abnormally narrow hands and[]

  • Deletion of the Long Arm of Chromosome 18

    In particular, vocabulary and the production of speech (expressive language skills) may be delayed.[] The might also have seizures, low muscle tone (hypotonia), speech and language delays, obesity, and short stature.[] In addition, Chromosome 18q- syndrome is often characterized by low muscle tone (hypotonia); sudden episodes of uncontrolled electrical activity in the brain (seizures); moderate[]

  • Short Chain Acyl CoA Dehydrogenase Deficiency

    None developed epilepsy or behavioral disorders, and three patients had isolated speech delay. Hypoglycemia occurred in two patients, both in the neonatal period.[] Of those reported cases, hypoglycemia, developmental delay, and muscle hypotonia are the most common indicated features.[] She was hospitalized once with pneumonia, once with gastrointestinal symptoms, and had speech delay.[]

  • Congenital Cataract-Hearing Loss-Severe Developmental Delay Syndrome

    A child with speech delay has speech development that is typical of a normally developing child of a younger chronologic age; the speech-delayed child's skills are acquired[] Muscle tone vs. muscle strength The low muscle tone associated with hypotonia must not be confused with low muscle strength.[] These problems may include migraine headaches, seizures, developmental delays, speech delays and very rarely ischemic strokes.[]

  • Hyperphosphatasia - Intellectual Disability Syndrome

    […] myelinization (in some patients), speech delay (in some patients), and no speech development (in most patients).[] In addition to eye abnormalities, affected individuals may also have neurological abnormalities including diminished muscle tone (hypotonia), delays in speech development,[] In early childhood, the diagnosis is based on substantial developmental delays, including motor, cognitive, and speech delays.[]
