Strawberry skull in Edwards syndrome

Area of Science:

• Genetics
• Prenatal Diagnosis
• Human Genetics

Background:

• Edwards syndrome, or trisomy 18, is the second most frequent chromosomal disorder after Down syndrome.
• It results from an extra copy of chromosome 18, presenting as full, mosaic, or partial trisomy 18q.
• The condition has a high prevalence, with significant fetal loss and pregnancy terminations post-diagnosis.

Observation:

• This report details a specific case of Edwards syndrome.
• The diagnosis was established during a standard antenatal ultrasound examination.
• This underscores the utility of routine prenatal screening.

Findings:

• Prenatal diagnosis of trisomy 18 is feasible through routine antenatal scans.
• Early identification allows for informed decision-making regarding pregnancy management.
• The case presentation reinforces established epidemiological data for Edwards syndrome.

Implications:

• Routine antenatal screening plays a crucial role in identifying trisomy 18.
• Timely diagnosis facilitates genetic counseling and family planning.
• Further research into trisomy 18 management and outcomes remains important.
