Infantile hypophosphatasia

Infantile hypophosphatasia is an autosomal recessive disorder caused by mutations of the ALPL gene. Of all hypophosphatasias this is the most severe form that manifests in early childhood and is lethal in about 50% of cases.

Management

For therapy Strensiq® (asfotase alfa) is available.
