Renal tubular acidosis are forms of metabolic acidosis characterized by an impairment of urinary acidification due to a lack of urine excretion of protons or loss of bicarbonates. Primary distal renal acidosis (dRTA) is characterized by hyperchloremic metabolic acidosis due to failure in proton excretion, variably severe nephrocalcinosis and/or nephrolithiasis associated with hypercalciuria and...
Background and Objective: TMC1 gene mutations are known as the most common causes of autosomal recessive non-syndromic hearing loss (ARNSHL) in different populations. According to large size of the TMC1 gene and the large number of identified mutations in this gene, application of polymorphic markers is suggested for carrier detection and prenatal diagnosis in families. In this study, informati...
Mutations in GJB2, encoding connexin 26 (Cx26), cause both autosomal dominant and autosomal recessive nonsyndromic hearing loss (ARNSHL) at the DFNA3 and DFNB1 loci, respectively. Most of the over 100 described GJB2 mutations cause ARNSHL. Only a minority has been associated with autosomal dominant hearing loss. In this study, we present two families with autosomal dominant nonsyndromic hearing...
Alport syndrome (ATS) is a type-IV collagen inherited disorder, caused by mutations in COL4A3 and COL4A4 (autosomal recessive) or COL4A5 (X-linked). Clinical symptoms include progressive renal disease, eye abnormalities and high-tone sensorineural deafness. A renal histology very similar to ATS is observed in a subset of patients affected by mutations in MYH9, encoding non-muscle-myosin Type II...
Objective(s): Jervell and Lange–Nielsen syndrome is an autosomal recessive disorder caused by mutations in KCNQ1 or KCNE1 genes. The disease is characterized by sensorineural hearing loss and long QT syndrome. Methods: Here we present a 3.5-year-old female patient, an offspring of consanguineous marriage, who had a history of recurrent syncope and congenital sensorineural deafness. The patient ...
Prelingual non-syndromic (isolated) deafness is the most frequent hereditary sensory defect. In >80% of the cases, the mode of transmission is autosomal recessive. To date, 14 loci have been identified for the recessive forms (DFNB loci). For two of them, DFNB1 and DFNB2, the genes responsible have been characterized; they encode connexin 26 and myosin VIIA, respectively. In order to evaluate t...
