Hypophosphatasia: Novel Mutation Associated With An Atypical Newborn Presentation
We report the case of a preterm newborn
in whom a corneal opacity was detected at birth. Blood tests performed to investigate this finding showed low alkaline
phosphatase concentrations. The corneal opacity disappeared within a week but alkaline phosphatase remained persistently
low. With persistently decreased levels of alkaline phosphatase, upon suspicion of hypophosphatasia, plain radiography
detected changes suggestive of rickets. Sequencing of the ALPL gene revealed a heterozygous variant that has not been
described in the literature to date.</p>
<p>Our patient’s condition could be an atypical neonatal form of the syndrome, with a mild phenotype, very different from the
classic neonatal form which can lead to severe skeletal disease and respiratory failure. However, it could also be an early
diagnosis of the childhood form, with better prognosis.</p>
