Mutations in enzymes involved in the biosynthesis of CoQ10 genes are associated with these deficits. The clinical presentation of this rare autosomal recessive disorder is heterogeneous and depends on the gene involved. Mutations in the <jats:italic>COQ2, COQ6, PDSS2<\/jats:italic>, and <jats:italic>ADCK4<\/jats:italic> genes are responsible for steroid\u2010resistant nephrotic syndrome (SRNS), which is associated with extra\u2010renal symptoms. Previous studies have reported <jats:italic>COQ6<\/jats:italic> mutations in 11 patients from five different families presenting with SRNS and sensorineural deafness.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case reports<\/jats:title><jats:p>Our study reports the cases of two brothers of Turkish origin with renal failure and sensorineural deafness associated with <jats:italic>COQ6<\/jats:italic> mutations responsible of CoQ10 deficiency. Optical symptoms were present in the eldest, that improved with Idebenone.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion\/Discussion<\/jats:title><jats:p>For the first time, <jats:italic>COQ6<\/jats:italic> mutation with optical involvement is associated with renal and hearing impairment. Although the response to replacement CoQ10 therapy was difficult to evaluate, we think that this treatment was able to stop the disease progression in both patients, and even to prevent the occurrence\/development of optical and neurological impairment in the younger brother. Mitochondrial dysfunction secondary to CoQ10 deficiency should always be suspected in patients with SRNS and extra\u2010renal symptoms. Early recognition of this genetic SRNS is mandatory since SRNS can be avoided by adequate treatment based on CoQ10 supplement or an analogue. All cases of primary CoQ10 deficiency should be treated at an early stage to limit the progression of lesions and prevent the emergence of new symptoms.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jmd2.12068","type":"journal-article","created":{"date-parts":[[2020,5,5]],"date-time":"2020-05-05T11:46:29Z","timestamp":1588679189000},"page":"37-44","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["<i>COQ6<\/i>
