To date, the syndrome has only been reported in one family with five members affected in three generations. The first patients were two brothers that had an abnormally-shaped head due to coronal craniosynostosis. Their mother, maternal aunt, and maternal grandmother were also found to have the syndrome. The signs and symptoms varied from person to person; however, the signs and symptoms included coronal craniosynostosis, small middle part of the face (midfacial hypoplasia), and short fingers (brachydactyly).The inheritance is thought to be autosomal dominant. No genes have been identified for this syndrome. Treatment included surgery to correct the craniosynostosis. No issues with development and normal intelligence were reported. This is an n-of-1 use case where only one patient or family has been described with this disorder. 2026-02-01 craniosynostosis - dysmorphism - brachydactyly craniosynostosis brachydactyly craniosynostosis-dysmorphism-brachydactyly syndrome SCTID:720814001 MONDO:0023243 This term is scheduled for obsoletion based on the fact that it is a historical diseaseAfter obsoletion, this term will not have a replacement ID, but one could consider the following term: Muenke syndrome-MONDO:0011274 Orphanet:1535
