Alport syndrome is a genetically heterogenous disorder resulting from variants in genes coding for alpha-3/4/5 chains of Collagen IV, which results in defective basement membranes in the kidney, cochlea and eye. The syndrome has different inheritance patterns and historically, was thought of as a disease affecting solely males. A 15-year-old female presented with pedal oedema, hypertension and proteinuria. She underwent a kidney biopsy which showed findings in keeping with focal segmental glomerulosclerosis. Her condition was refractory to steroids. Steroid-resistant nephrotic syndrome genetics were sent, revealing a rare pathogenic variant in the COL4A5 gene. Heterozygous females with X-linked Alport syndrome can develop chronic kidney disease and hearing loss. Clinicians should be mindful when reviewing kidney histology to include Alport syndrome as a differential for female patients. COL4A3-5 genes should be included in allsteroid-resistant nephrotic syndrome genetic panels.
