Objectives
Narrative objectives1
The primary objectives of this study are to investigate the following matters in perinatal lethal/non-lethal and infantile HPP in clinical course:
>To identify candidate predictive markers that could correlate with the disease burden of bone manifestation in HPP
>To investigate bone calcification and bone quality by BMD, BMC and bone metabolism markers other than RSS and RGI-C, regardless of therapeutic intervention including Asfotase alfa treatment

The secondary objectives of this study are to investigate the following matters in perinatal lethal/non-lethal HPP and infantile HPP in clinical course:
>To search for candidate factors to affect motor functions development
>To investigate association of the extent of whole body bone calcification with dental manifestations
>To investigate disease burden of developmental/mental delay, and to search for the factors associated with developmental/mental delay

Assessment
Primary outcomes
>Evaluation of bone based on radiographs using Rickets Severity Scale (RSS) and modified Radiographic global impression of change(mRGI-C) as a validated scale of HPP(0, 12, 24, 48, 72, 96week)
>Time until intervention with artificial respiratory therapy becomes necessary in the patients who have not received artificial respiratory therapy at the beginning of the observation period (0, 12, 24, 48, 72, 96week)
>In the patients who have necessitated artificial respiratory therapy at the beginning of the observation period or during the observation period, evaluation will be made based on the status of artificial respirator, respiratory support time (including the duration of the use of artificial respirator or the duration of oxygen inhalation), frequency of ventilation with artificial respirator or oxygen flow rate, pressure of artificial respirator, and fraction of inspiratory oxygen (FiO2). (0, 12, 24, 48, 72, 96week)
>Body weight, height, arm span, head circumference and chest circumference will be determined and physical development will be examined and evaluated. (0, 12, 24, 48, 72, 96week)
>Intellectual and motor development will be evaluated using Kyoto Scale of Psychological Development (K scale). (48, 96week)
>The clinical course of HPP in teeth will be examined and evaluated on the basis of the clinical findings such as the number, time and site of teeth lost, depth of the periodontal pockets, periodontal bleeding, tooth mobility and dental formula, and imaging evaluation of morphological abnormalities of teeth and dental age on radiographs. (48, 72, 96week)
>Gross motor function test will be conducted using Denver IIgross motor development scale. (24, 48, 72, 96week)
>Hearing test will be conducted using the auditory brain stem response (ABR) to evaluate the status of impaired hearing. (0, 24week)
Key secondary outcomes
Health Outcomes
>ADL will be evaluated using PedsQL and CHAQ. (96week)
Biomarkers
>PLP, PL (0 or cord blood sample, 12, 24, 48, 72, 96week) and metabolites detected by metabolome technology in plasma 0 or cord blood, 12, 48week will be determined to evaluate the usefulness as metabolic markers
>P1NP, CTX, Sclerostin, FGF23 and factors related with bone metabolism tested by multi-plex analysisin serum will be determined as bone metabolism markers to investigate the usefulness as markers reflecting bone quality (0 or cord blood, 12, 48week)
>Bone mineral content and bone mineral density will be determined as the markers for ossification using dual-energy X-ray absorptiometry, and the bone mass in the process of ossification in HPP patients will be quantified. Moreover, Lean Body Mass will be determined by DXA as a quantitative marker for muscle mass (48, 96week)
