PURPOSE: To describe the clinical features of and identify a novel mutation in Bardet-Biedl syndrome 7 gene (BBS7) in a Chinese family.
METHODS: Nineteen individuals at risk for inheriting Bardet-Biedl syndrome (BBS) in a Chinese family participated in the study. Physical examination was performed and blood was drawn for DNA extraction. Linkage analysis was conducted for all known BBS loci, and mutation screening of BBS7 gene and BBS12 gene was performed.
RESULTS: A Chinese family with inherited BBS was identified. After performing linkage analysis on all 13 known loci, we found the disease phenotype of a Chinese family with BBS linked to a locus where BBS7 and BBS12 genes locate.
CONCLUSIONS: This study describes a novel mutation in BBS7 causing BBS in a Chinese family. This is the first report that a mutation in a BBS gene causes BBS in a Chinese population. These results expand the spectrum of human disease associated with mutations of BBS7 since the initial three mutations in BBS7 were first identified in 2003.
