Prenatal diagnosis of Bardet–Biedl syndrome in a case of hyperechogenic kidneys: Clinical use of DNA sequencing
نویسندگان
چکیده
Bardet-Biedl syndrome (BBS) is a ciliopathy that is responsible for multiple visceral abnormalities. This disorder is defined by a combination of clinical signs, many of which appear after several years of development. BBS may be suspected antenatally based on routine ultrasound findings of enlarged hyperechogenic kidneys and postaxial polydactyly.

Bardet-Biedl syndrome (BBS) is an autosomal recessive ciliopathic human genetic disorder with variable expression that is difficult to diagnose in pregnancy without known risk factors. Homozygosity testing has been shown to be a useful tool in identifying BBS mutations and candidate genes in affected individuals. We present the first case of prenatal diagnosis of BBS in consecutive pregnancies ...

Bardet-Biedl syndrome (BBS) is one of the rare autosomal recessive disorders that affect multiple organs of the body. The signs and symptoms of this condition vary among affected individuals, even among members of the same family. We present a case of BBS with features of hypogonadism and features such as marked central obesity, retinitis pigmentosa, polydactyly, renal abnormalities and mental ...

Discovery of cell free fetal DNA in 1997 has deeply changed the outlook of prenatal diagnosis approaches as most of the clinically established screening tests are not sensitive/specific enough while the current practical diagnostic tests are also invasive in their nature. The most common prenatal screening test is routinely practiced for the diagnosis of Down syndrome (DS) which includes a 10% ...
متن کاملComprehensive Molecular Diagnosis of Bardet-Biedl Syndrome by High-Throughput Targeted Exome Sequencing
Bardet-Biedl syndrome (BBS) is an autosomal recessive disorder with significant genetic heterogeneity. BBS is linked to mutations in 17 genes, which contain more than 200 coding exons. Currently, BBS is diagnosed by direct DNA sequencing for mutations in these genes, which because of the large genomic screening region is both time-consuming and expensive. In order to develop a practical method ...
