摘要：
We describe the case of a 21-year-old male with hypocalcaemia, hyperphosphataemia, recurrent limb twitch, deafness, proteinuria, increased serum creatinine and urea nitrogen levels, and shrinkage of both kidneys. Brain computed tomography showed intracranial calcifications. The patient was diagnosed with hypoparathyroidism, sensorineural deafness and renal dysplasia (HDR) syndrome. DNA sequence analysis of the GATA3 gene showed a novel de novo mutation, c. 529dupC (p. Arg177profs*126), in exon 2, resulting in a frameshift mutation with a premature stop codon after a new 126 amino acid sequence. We provide further evidence that HDR syndrome is caused by haploinsufficiency of GATA3.
