A combination of hypoparathyroidism, sensorineural deafness, and renal dysplasia has been considered to be a new syndrome inherited in an autosomal dominant fashion; we name the condition ''HDR syndrome.'' We describe a Japanese girl who has HDR syndrome associated with de novo del(10)(p13). The chr

โฆ Synopsis
We report on a Japanese boy with HDR syndrome (hypoparathyroidism, sensorineural deafness, renal dysplasia) and recurrent cerebral infarctions in the basal ganglia. The patient experienced cerebral infarctions four times between age 7 months and age 20 months. Chromosome analysis of the patient demonstrated a 46,XY,del(10)(p14p15.1) de novo. This suggests that the putative gene responsible for HDR syndrome is located at 10p14-p15.1. Am. J. Med. Genet. 86: 427-429, 1999.
