Genitopatellar syndrome: a case report of a rare entity with 11 years of follow-upTo, Michael; Negandhi, Rajiv; Cheung, Kenneth; Cheung, Wai Yuen; Chow, WangJournal of Pediatric Orthopaedics B: July 2013 - Volume 22 - Issue 4 - p 333–338 doi: 10.1097/BPB.0b013e3283528d40 Femur & Knee Abstract Author Information Genitopatellar syndrome is one of the syndromes described in the last decade. It is characterized by agenesis of the corpus callosum, absent or hypoplastic patellae, extremity contractures, skeletal anomalies, urogenital anomalies, and facial dysmorphic features. While writing this report, only 15 cases have been reported in the literature. The etiology, clinical features, management, and natural history of this syndrome are not yet well established. Past reports in the literature have not been able to identify the exact genetic etiology but it somewhat coincides with nail patella syndrome and short patella syndrome. We would like to introduce this terminology to the orthopedic community and highlight the clinical features of the genitopatellar syndrome. To the best of our knowledge, this is a single case report with the longest follow-up of 11 years in the literature.
