large parietal foramina superior and slightly medial to the orbits


An autosomal dominant condition (OMIM:168500) characterised by large oval defects of the parietal bones caused by deficient ossification around the parietal notch, which is normally obliterated at the 5th fetal month.  

Molecular pathology Defects of:

MSX2—which encodes a transcription repressor that ensures a balance between survival and apoptosis of neural crest-derived cells required for craniofacial morphogenesis, that also plays a role in limb-pattern formation, cause parietal foramina 1 (PF1).

ALX4—which encodes a homeodomain transcription factor that may play a role in craniofacial development, cause PF2. 

Synonyms Catlin marks, foramina parietalia permagna, PF—symmetric, PFM
