Fluorescent in situ hybridization (FISH), chromosomal microarray analysis (CMA), and exome sequencing (ES) were nondiagnostic. Combined optical genome mapping (OGM) and genome sequencing (GS) showed a complex rearrangement including an X chromosome with a 22.5\u2009kb deletion in band Xq28 replaced by a 61.4\u2009kb insertion of duplicated chromosome 7p22.3 material. The deletion removes the distal 3\u2032 untranslated region (UTR) of <jats:italic>FUNDC2<\/jats:italic>, the entire <jats:italic>CMC4<\/jats:italic> and <jats:italic>MTCP1<\/jats:italic>, and the first five exons of <jats:italic>BRCC3<\/jats:italic>. Transcriptome analysis revealed absent expression of <jats:italic>CMC4<\/jats:italic> and <jats:italic>MTCP1<\/jats:italic> and <jats:italic>BRCC3<\/jats:italic> with normal transcript level of <jats:italic>FUNDC2.<\/jats:italic> The inserted duplication includes only one known gene: <jats:italic>UNCX.<\/jats:italic> Similar overlapping Xq28 deletions have been reported to be associated with Moyamoya disease (MMD), short stature, hypergonadotropic hypogonadism (HH), and facial dysmorphism. Although he has short stature, our patient does not have signs of Moyamoya arteriopathy or hypogonadism. The structurally abnormal X chromosome was present in his mother, but not in his unaffected brother, maternal uncle, or maternal grandparents. We propose that the combination of his absent Xq28 and duplicated 7p22.3 genomic material is responsible for his phenotype. This case highlights the potential of combined OGM and GS for detecting complex structural variants compared with standard of care genetic testing such as CMA and
