Cytogenetic study in cases with recurrent abortion in Saudi Arabia

Area of Science:

• Genetics and Reproductive Medicine
• Human Cytogenetics
• Clinical Genetics

Background:

• Recurrent pregnancy loss (RPL) is a significant reproductive health issue.
• Parental chromosomal abnormalities are a known cause of RPL.
• Previous research on RPL and chromosomal abnormalities has not focused on the Arab Peninsula.

Purpose of the Study:

• To investigate the prevalence and types of chromosomal abnormalities in Saudi couples experiencing recurrent abortion.
• To compare findings with international data.
• To inform clinical practice and cytogenetic screening strategies in the region.

Main Methods:

• A cytogenetic study was conducted on 193 consecutive Saudi couples.
• Participants presented with a history of repeated fetal loss at King Khalid University Hospital, Riyadh.
• Standard cytogenetic analysis was performed.

Main Results:

• The frequency of chromosomal abnormalities identified in this Saudi cohort was comparable to global reports.
• The specific nature of these abnormalities and their correlation with obstetric history were analyzed.
• No significant deviation from worldwide frequencies was observed.

Conclusions:

• This study highlights the importance of considering chromosomal abnormalities in recurrent fetal loss cases within the Arab Peninsula.
• Findings support the integration of cytogenetic screening into the diagnostic workup for couples with repeated abortions.
• Recommendations are provided for prioritizing cytogenetic evaluation in clinical settings.
