Identification of a novel insertion mutation in GATA3 with HDR syndrome.
Recently, a member of the GATA-binding family of transcription factors was shown to be involved in human hypoparathyroidism, sensorineural deafness, and renal abnormality (HDR) syndrome. We report here a Japanese family in which two of the members are affected with HDR syndrome. Sequence analysis of GATA3 showed a heterozygous novel mutation in this family: an unusual mutation at exon 3 (709insC) resulting in a premature stop at codon 302 with a loss of both of the zinc finger domains.
