title: A family with two sisters with collagenofibrotic glomerulonephropathy.
abstract: Collagenofibrotic glomerulonephropathy is a recently recognized disease entity. Although an autosomal recessive inheritance pattern has been suggested for this condition, there are few reports of familial cases. Only four pairs of child siblings, with histological confirmation of the glomerular lesions, have been reported. The current report describes a family including two sisters with histological evidence of collagenofibrotic glomerulonephropathy. Serum concentrations of the procollagen III peptide were elevated in the affected sisters, whereas their parents and other siblings demonstrated neither proteinuria nor increased blood levels of the procollagen III peptide. Our findings support an autosomal recessive pattern of inheritance for this type of glomerulonephropathy. They also suggest that the serum concentration of the procollagen III peptide is a useful marker for collagenofibrotic glomerulonephropathy.
