Bardet-Biedl syndrome (BBS) is a genetically heterogeneous disorder characterized by polydactyly, obesity, rod-cone dystrophy, and mental retardation. Twenty-one genes have been identified as causing BBS. This study collected a BBS pedigree from two patients and performed whole-exome sequencing on one patient. We identified a novel homozygous variant c.1114C>T (p.Q372X) in the BBS9 of the two siblings. This variant was confirmed and completely cosegregated with the disease of this family by Sanger sequencing. We report a novel homozygous variant c.1114C>T in the BBS9 gene in a Chinese family.

AbstractBardet–Biedl syndrome (BBS) is a rare genetically heterogeneous ciliopathy which accompanies retinitis pigmentosa (RP). However, the BBS5 mutation remains unclear in Iranians with BBS. The purpose of study is to evaluate genetic analyses of a BBS Iranian family using targetted exome sequencing (TES). A male 11-year-old proband and three related family members were recruited. Biochemical tests, electrocardiography and visual acuity testing, such as funduscopic, fundus photography (FP), optical coherence tomography (OCT), and standard electroretinography, were conducted. Molecular analysis and high-throughput DNA sequence analysis were performed. The proband was diagnosed with possible BBS based on the presence of three primary features and two secondary features. The TES analysis of the proband with BBS resulted in the identification of a novel, homozygous splicing variant c. 208+2T>C of the BBS5 gene (NM_152384.2) in this Iranian BBS family. This variant was confirmed and was completely co-segregated with the disease in this family by Sanger sequencing. Thus, we report a novel, homozygous splicing site variant c.208+2T>C in the BBS5 gene for the first time in the Iranian family.

Bardet-Biedl syndrome (BBS) is a rare autosomal recessive disorder known to be caused by mutations in at least 19 BBS genes. We report the genetic analysis of a patient with indisputable features of BBS including cardinal features such as postaxial polydactyly, retinitis pigmentosa, obesity, and kidney failure. Taking advantage of next-generation sequencing technology, we applied whole exome sequencing (WES) with Sanger direct sequencing to the proband and her unaffected mother. A pair of heterozygous nonsense mutations inBBS2gene was identified in the proband, one being novel and the other recurrent. The novel mutation, p.Y644X, resides in exon 16 and was also found in the heterozygous state in the mother. This mutation is not currently found in the dsSNP and 1000 Genome SNP databases and is predicted to be disease causing byin silicoanalysis. This study highlights the potential for a rapid and precise detection of disease causing gene using WES in genetically heterogeneous disorders such as BBS.
