If you dont develop any complications from surgery, youll likely be able to return to school or work in about 1 to 3 weeks after surgery. To evaluate the effects of the p.A12D substitution on signal peptide function, we analyzed the protein sequence of FGF23 using the signal peptide prediction packages SignalP, PrediSi, Signal-CF and Signal-3L.

Possible complications include: Because prognathism is a congenital condition (present at birth), theres nothing you can do to prevent it from happening. A rare, genetic, developmental defect during embryogenesis disorder characterized by abnormal forward projection of the mandible beyond the standard relation to the cranial base, with lower incisors often overlapping the upper incisors, that is inherited in an autosomal dominant manner. Due to the highly variable subphenotypes (mandibular protrusion, maxillary retrusion, or a combination of both) and clinical heterogeneity of MP, genetic mechanism for this malformation remains uncertain.
