Kyphoscoliotic Ehlers–Danlos syndrome and 17p13.3 microduplication share multiple clinical features such as muscle hypotonia, cleft palate, and growth impairment. This paper describes a patient who was first diagnosed with the duplication and a decade later also with FKBP14-kEDS. The latter was initially overlooked due to the pathogenic significance attributed to the duplication and to the fact that, at the time of the first diagnosis, this specific form of kEDS had yet to be discovered. The patient’s progressive kyphoscoliosis and severe joint laxity were the clinical features that prompted the patient’s physiatrist to reassess the genetic work-up. This extreme latency caused inaccurate management in the patient’s follow-up program, which ultimately may have resulted in preventable clinical complications. This report underlines the importance of remaining up-to-date with patient status, reviewing old cases, and relying on specialist advice to reach a correct diagnosis.
