Introduction: Focal dermal hypoplasia (FDH) is a genodermatosis also known as Goltz-Gorlin syndrome caused by pathogenic variants in the gene and inherited in an X-linked dominant manner. Given the course of X-linked dominant inheritance, affected males can only survive in the state of mosaicism for a pathogenic variant or in the presence of XXY karyotype. FDH is a multisystemic disorder in which cutaneous, ocular, and skeletal systems are primarily affected. Patients also may display intellectual disability and central nervous system abnormalities, yet most may have normal mental development.
Case Presentation: We report on a currently 11-year-old female patient with a novel missense heterozygous variant who exhibited classical ectodermal, skeletal, and ocular findings in addition to mild intellectual disability, left-side diaphragm eventration, and puberty precox, a finding yet unreported in the literature.
Conclusion: With this report, we aimed to expand the mutational spectrum and give insight into the importance of neurologic and skeletal system evaluation among other clinical features of FDH. Although gastrointestinal and genitourinary problems can occur during the course of the disease, to our knowledge, left-side diaphragm eventration and puberty precox are new features that have not been reported previously.
