Balanced chromosomal rearrangements with a breakpoint located upstream of the sex determining region Y-box 9 (SOX9) gene on chromosome 17q24.3 are associated with skeletal abnormalities, campomelic dysplasia (CMPD), or acampomelic campomelic dysplasia (ACMPD). We report on a female patient with a reciprocal translocation of t (11; 17) (p15.4; q24.3), who was diagnosed with acampomelic campomelic dysplasia. The 34-year-old Japanese patient presented with distinct skeletal abnormalities, profound intellectual disability, and female phenotype despite the presence of Y chromosome and the sex determining region Y (SRY) gene. Her menarche started at 33 years and 4 months after hormone therapy of estrogen therapy followed by estrogen progesterone therapy. By conducting whole genome sequencing followed by Sanger sequencing validation, we determined the precise breakpoint positions of the reciprocal translocation, one of which was located 203 kb upstream of the SOX9 gene. Considering the phenotypic variations previously reported among the CMPD/ACMPD patients with a chromosomal translocation in the vicinity of SOX9, the identified translocation was concluded to be responsible for all major phenotypes observed in the patient.
