Description : Primary coenzyme Q10 deficiency-6 is an autosomal recessive disorder characterized
by onset in infancy of severe progressive nephrotic syndrome resulting in end-stage
renal failure and sensorineural deafness. Renal biopsy usually shows focal segmental
glomerulosclerosis (FSGS). Some patients may show a favorable response to oral coenzyme
Q supplementation (summary by Heeringa et al., 2011). For a general phenotypic description
and a discussion of genetic heterogeneity of focal segmental glomerulosclerosis and
nephrotic syndrome, see FSGS1 (603278) and NPHS1 (256300).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the homolog of the S. cerevisiae COQ6 gene (COQ6, 614647.0001);
