The first Korean case with Floating-Harbor syndrome with a novel SRCAP mutation diagnosed by targeted exome sequencing. Korean J Pediatr. 2018 Sep 16;: Authors: Choi EM, Lee DH, Kang SJ, Shim YJ, Kim HS, Kim JS, Jeong JI, Ha JS, Jang JH Abstract Floating-Harbor syndrome is a rare autosomal dominant genetic disorder associated with SRCAP mutation. To date, approximately 50 cases of Floating-Harbor syndrome have been reported, but none have been reported in Korea yet. Floating-Harbor syndrome is characterized by delayed bony maturation, unique facial features, and language impairment. Here, we present a six-year-old boy with a triangular face, deep-set protruding eyes, low-set ears, wide nose with narrow nasal bridge, short philtrum, long thin lips, clinodactyly, and developmental delay that was transferred to our pediatric clinic for genetic evaluation. He showed progressive delay in the area of language and cognition-adaption as he grew. He had previously undergone chromosomal analysis at another hospital due to his language delay, but his karyotype was normal. We performed targeted exome sequencing, considering several syndromes with similar phenotypes. Library preparation was performed with the TruSight One sequencing panel (Illumina, USA), which enriches the sample for about 4800 genes of clinical relevance. Massively parallel sequencing was conducted with NextSeq (Illumina, USA). An identified variant was confirmed by Sanger sequ...
