Case in brief
A fetus was suspected of having short-rib thoracic dysplasia (SRTD) based on ultrasound findings at 13 weeks of gestation. Prenatal genetic testing identified a pathogenic variant in the DYNC2H1 gene. Following an abortion, post-abortion examination and X-ray findings confirmed the diagnosis as short-rib thoracic dysplasia 3 (SRTD3). This case highlights the potential for early detection through ultrasound and genetic testing.
What made this case unusual
This case is notable for the early diagnosis of SRTD at 13 weeks of gestation, which is rarely reported.
Diagnostic / clinical pearl
Clinicians should consider early ultrasound screening and genetic testing for suspected short-rib thoracic dysplasia to enable timely diagnosis.
Why it matters
Early detection of genetic conditions like SRTD can inform prenatal assessments and potentially reduce the incidence of birth defects.
