A case of thanatophoric dysplasia: the early prenatal 2D and 3D sonographic findings and molecular confirmation of diagnosis

Fetal Diagn Ther. 2008;24(1):71-3. doi: 10.1159/000132411. Epub 2008 May 27.

Abstract

Objective: To present the early 2D and 3D ultrasound findings and the molecular confirmation in a case of thanatophoric dysplasia.

Methods: On ultrasound examination, there was frontal bossing, increased nuchal translucency and short limbs at 12 weeks' gestation and a small thorax and short and bowed long bones on 3D at 16 weeks. Amniocentesis and DNA analysis confirmed the mutation of FGFR3 gene indicating thanatophoric dysplasia.

Results: After medical termination of pregnancy, the postmortem X-ray and pathology examination findings were consistent with the diagnosis.

Conclusion: 3D anatomy scan and molecular confirmation may be helpful in early diagnosis and genetic counseling of thanatophoric dysplasia.
