Summary

Individuals with trigonocephaly have a keel-shaped forehead with wide biparietal diameter, resulting in a triangular shape of the head. Trigonocephaly results from premature closure of the metopic sutures and usually occurs sporadically (summary by Frydman et al., 1984). Genetic Heterogeneity of Isolated Trigonocephaly Also see trigonocephaly-2 (TRIGNO2; 614485), caused by mutation in the FREM1 gene (608944) on chromosome 9p22. [from OMIM]
