Objective: To report our experience of the prenatal diagnosis of X-linked dominant chondrodysplasia punctata (CDPX2) and highlight its variable phenotypic presentation.
Methods: We report the sonographic features of three female fetuses affected with CDPX2. The ultrasound, radiographic and pathological findings were compared.
