424 Possible Causes for Muscle Hypotonia, Polyhydramnios

  • Hypophosphatasia

    Young children and infants affected with severe forms of HPP, but also adults often present with myopathy characterized by hypotonia or muscle weakness.[] Other clinical findings included polyhydramnios, blue sclerae and spurs in the mid-portion of the forearms and lower legs.[] These infants have a history of poor feeding and failure to thrive , developmental delays, and muscle weakness. Hypotonia has also been reported.[]

  • Pallister-Killian Syndrome

    Symptoms of Pallister-Killian syndrome can vary, although most individuals experience low muscle tone (hypotonia), intellectual disabilities, distinctive facial features,[] PKS may be suspected based on the prenatal ultrasound detection of polyhydramnios and diaphragmatic hernia, possibly associated with rhizomelic micromelia.[] This disorder is characterized by extremely weak muscle tone (hypotonia) in infancy and early childhood, developmental delay/intellectual disability, distinctive facial features[]

  • Beckwith-Wiedemann Syndrome

    Preterm delivery of a child with BWS is associated with an increased frequency of polyhydramnios, gestational hypertension, and vaginal bleeding in the mother.[] Polyhydramnios was obvious and the fetal heart enlarged progressively during pregnancy.[] Perlman syndrome is an overgrowth syndrome with high perinatal mortality, most frequent antenatal findings include polyhydramnios, macrosomia, visceromegaly, nephromegaly[]

Hypotonia is often a sign of a worrisome problem. The condition can affect children or adults.[]

  • X-Linked Centronuclear Myopathy

    In affected males, first symptoms of the classical type usually started postnatally with severe weakness, muscle hypotonia, feeding difficulties, and respiratory failure.[] Signs of antenatal onset are frequent and comprise reduced fetal movements and polyhydramnios. Thinning of the ribs is observed on chest radiographs of the newborn.[] Individuals with this condition have muscle weakness (myopathy) and decreased muscle tone (hypotonia) that is usually evident at birth.[]

  • Urioste Martinez-Frias Syndrome

  • Glycogen Storage Disease Type 4

    Clinical features are muscle hypotonia and cirrhosis. Death from liver disease usually occurs before age 2.[] This form is characterized by polyhydramnios, neonatal hypotonia, and neuronal involvement; hepatopathy is uncommon, and the babies usually die between 4 weeks and 4 months[] Excess fluid may build up around the fetus (polyhydramnios) and in the fetus' body.[]
