[Distal renal tubular acidosis: report of 3 cases].

Three observations of R.T.A. with nerve deafness are reported. Case 1 and 2 concern consanguinous brothers whose parents are not affected, which confirm the syndrom as an autosomal recessive entity. The third, sporadic, case relates to a 13-year-old non consanguinous girl. Metabolic abnormalities and renal evolution with nephrocalcinosis was such as in Albright disease. However a progressive nerve deafness makes distinction. The authors underline the importance of this sometimes difficult distinction for genetic counseling.
