A novel variant in FN1 in a family with fibronectin glomerulopathy.

Glomerulopathy with fibronectin deposits (GFND) is a rare glomerular disorder. We report a 28-year-old male diagnosed with GFND by mass spectrometry on kidney biopsy tissue. Whole-exome sequencing (WES) identified that a previously undescribed FN1 gene mutation (c.3051G > T, p.W1017C) was likely responsible for this patient's fibronectin glomerulopathy. We discuss the implications of this novel variant of FN1 and the importance of WES to identify a mutation in a gene of interest. [ABSTRACT FROM AUTHOR]
