Genetic Risks Associated with Consanguinity in Kosovo Region

Couples from the Kosovo region who are related (consanguineous) have an increased risk of having children with autosomal recessive genetic disorders and should be offered genetic counseling and carrier screening before conception to identify potential risks.

Understanding Consanguinity and Genetic Risk

Consanguineous marriages (relationships between blood relatives, particularly second cousins or closer) increase the risk of autosomal recessive disorders in offspring. This occurs because related individuals are more likely to carry the same recessive gene mutations inherited from common ancestors.

Risk Assessment

  • The risk of major congenital anomalies in offspring of consanguineous couples is approximately 6-11%, compared to 2-3% in the general population 1
  • First-cousin marriages carry a higher risk (8.5% adjusted risk) compared to more distant consanguineous relationships (3.9% adjusted risk) 1
  • Prenatal detection of anomalies is higher than postnatal detection, highlighting the importance of comprehensive prenatal screening 1

Recommended Genetic Screening Approach

Preconception Screening

  • A thorough medical family history with follow-up of significant findings is essential 2
  • Exome-based carrier screening has demonstrated clinical value for consanguineous couples 3
  • Couples should be offered genetic screening appropriate for their ethnic background
  • Genetic counseling should be provided before marriage or conception when possible 4

During Pregnancy

  • Maternal-fetal serum marker screening
  • High-resolution fetal ultrasonography 2
  • Prenatal diagnostic testing (amniocentesis or chorionic villus sampling) if both parents are carriers for the same genetic disorder

Newborn Screening

  • Screening for impaired hearing
  • Screening for treatable inborn errors of metabolism 2

Cultural Considerations

When providing genetic counseling to Kosovo couples:

  • Respect cultural and religious perspectives on consanguinity
  • Provide information in a culturally sensitive manner
  • Ensure information is provided early, preferably before marriage 4
  • General practitioners are often considered the preferred healthcare professionals (54%) to provide this information 4

Genetic Counseling Process

  1. Risk assessment: Calculate specific risk based on degree of relationship
  2. Carrier testing: Identify if both partners carry mutations in the same gene
  3. Reproductive options discussion:
    • Natural conception with prenatal diagnosis
    • Preimplantation genetic diagnosis
    • Gamete donation
    • Adoption

Potential Challenges

  • Limited access to genetic services in certain communities
  • Cultural barriers to discussing genetic risks
  • Variable healthcare professional engagement in genetic risk counseling 5
  • Sustainability of specialized genetic services 5

While specific data on genetic disorders prevalent in the Kosovo region is limited in the provided evidence, the general principles of consanguinity-related genetic risk assessment and counseling apply. For optimal outcomes, couples should be referred to genetic counseling services before conception to understand their specific risks and options.
