Alport Syndrome Prevention: Genetic Counseling and Reproductive Options

Genetic Disorder Cannot Be Prevented, But Families Can Plan

Alport syndrome (COL4A3/4/5 mutations) causes hereditary nephritis, sensorineural hearing loss, and ocular abnormalities. Inheritance: X-linked (80%), autosomal recessive (15%), autosomal dominant (5%).

No Primary Prevention

The mutation is present at conception. Cannot be prevented post-fertilization.

Empowered Reproductive Choices

• Genetic Counseling: Determine inheritance pattern, recurrence risk, carrier status.
• Prenatal Diagnosis: CVS (10–13 wks) or amniocentesis (15–20 wks) for known familial mutation.
• Preimplantation Genetic Testing (PGT-M): IVF + embryo biopsy → select unaffected embryos.
• Donor Gametes/Adoption: Alternative family-building.
