Fibrillary/immunotactoid glomerulopathy can run in families. This rare kidney disease may have a better prognosis in familial cases compared to sporadic ones.

Area of Science:

  • Nephrology
  • Genetics
  • Immunology

Background:

  • Fibrillary/immunotactoid glomerulopathy (F/IG) is a rare kidney disease characterized by abnormal protein deposits in the glomeruli.
  • Its etiology is largely unknown, and it typically affects individuals without systemic diseases like amyloidosis.

Observation:

  • This report details the first known familial case of F/IG in a Chinese brother and sister.
  • Both siblings presented with significant proteinuria and showed transient improvement with immunosuppressive therapy.

Findings:

  • Human lymphocyte antigen typing did not reveal any shared genetic markers (haplotypes) between the siblings.
  • Despite the generally poor prognosis of F/IG, both patients maintained relatively preserved kidney function over several years.

Implications:

  • Fibrillary/immunotactoid glomerulopathy can have a genetic basis and present within families.
  • Familial F/IG might follow a more favorable clinical course regarding kidney function compared to sporadic instances.
