Intervention(s) |
Outcome(s)
Primary Outcome | -To verify the relationship between fetal ultrasound findings and postnatal motor development data by HPP disease type (Severe perinatal, benign perinatal, and infantile) and to perform an exploratory evaluation for the presence of ultrasound findings that affect motor development in patients. -To verify the relationship between fetal ultrasound findings and postnatal respiratory status data by HPP disease type (Severe perinatal, benign perinatal, and infantile) and to perform an exploratory evaluation for ultrasound imaging data that affect respiratory status. -Describe what are the baseline characteristics of perinatal/infantile HPP at the time of the abnormality detection from ultrasound imaging data -Asses what are the identifiable predictors of prognosis of HPP from ultrasound imaging data |
---|---|
Secondary Outcome | -To verify the relationship between fetal ultrasound imaging findings and patient disease types and to evaluate the predictability of HPP disease types after birth based on fetal ultrasound imaging findings. -To compare fetal ultrasound findings with the presence or absence of postnatal skeletal lesions and assess these associations descriptively. -To explore the therapeutic effect of asfotase alfa by HPP subtypes and assess these associations descriptively. -Asses if there is a correlation between clinical symptoms in the fetal period and post-natal motor function development grouped by the type of HPP -Assess prenatal and postnatal information on patients diagnosed with perinatal or infantile hypophosphatasia with or without enzyme replacement therapy and to examine the impact of prenatal information on postnatal HPP type, skeletal lesions, and asphotase alfa therapy |
