Abstract
BACKGROUND

Cleidocranial dysplasia (CCD) is an infrequent clinical condition with an autosomal dominant inheritance pattern. It is characterized by abnormal clavicles, patent sutures and fontanelles, supernumerary teeth, and short stature. Approximately 60%-70% of patients with CCD have mutations in the RUNX family transcription factor 2 gene. However, prenatal diagnosis of CCD is difficult when the family history is unknown.

CASE SUMMARY

We report a rare case of fetal CCD with an unknown family history, confirmed by prenatal ultrasonography and genetic testing at a gestational age of 16 weeks. The genetic reports indicated that the fetus carried pathogenic mutations in the RUNX family transcription factor 2 gene (c.674G>A). After careful consideration, the pregnant woman and her family decided to continue the pregnancy.

CONCLUSION

Definitive prenatal diagnosis of CCD should include family history, ultrasound diagnosis, and genetic analysis, especially if family history is unknown.

Core Tip: Cleidocranial dysplasia is rare and hidden condition, and many cases are gradually diagnosed after birth. Features include multiple teeth, partial or complete absence of the clavicle, delayed closure of the sagittal suture and fontanel, which have an adverse effect on physical and mental health. We report a rare case of fetal cleidocranial dysplasia with an unknown family history at 16 weeks gestation, confirmed by prenatal ultrasonography and genetic testing. This case can inform future clinicians to aid in timely and correct diagnosis.
