Abstract
Floating-Harbor syndrome (FHS) is an extremely rare genetic disorder connected with a distinctive facial appearance, various skeletal malformations, delayed bone age, and expressive language delays. It is caused by heterozygous mutations in the Snf2-related CREBBP activator protein (SRCAP) gene. The aim of this paper is to describe the case of a 14-year-old male with FHS, referring to a review of the literature, and to collect all reported symptoms. In addition, the orthodontic treatment of the patient is described. For this, the electronic databases PubMed and Scopus were searched using the keyword "Floating-Harbor syndrome". Similar to previous cases in the literature, the patient presented with short stature; a triangular face with a large bulbous nose; deep-set eyes and narrow eyelid gaps; a wide mouth with a thin vermilion border of the upper lip; and dorsally rotated, small ears. They also presented some less-described symptoms, such as macrodontia and micrognathia. Moreover, mild mental retardation, microcephaly, and delayed psychomotor development were found. On the basis of an extraoral, intraoral examination, X-rays, and CBCT, he was diagnosed with overbite, canine class I and angle class III, on both sides. To the best of our knowledge, orthodontic treatment of this disease has not been assessed in detail so far, so this is the first case.

Pharmgenomics Pers Med 2023; 16:1091-1096.

Abstract
Background Floating-Harbor syndrome (FHS) is a rare autosomal dominant inherited disease characterized primarily by short stature, delayed language development, and typical facial features. There are currently few case reports, diagnoses and treatments for these syndromes at home and abroad. Case Description This study reports a case of a boy with "growth and language development delay" as the predominant clinical manifestation. FHS was clinically diagnosed based on his growth hormone (GH) deficiency, significant bone age delay, left testicular hydrocele, and the whole exon gene in peripheral blood, which indicated heterozygous mutation of SRCAP gene. Following the treatment with recombinant human GH (rhGH), the child exhibited height increase benefits, and his articulation improved after language therapy. Conclusion Genetic testing facilitates early detection, diagnosis, and treatment of the FHS. Additionally, treatment with rhGH effectively increases the height of these children, and language rehabilitation is especially important for their language development.
