Six distinct BBS loci map to 11q13 (BBS1), 16q21 (BBS2), 3p13-p12 (BBS3), 15q22.3-q23 (BBS4), 2q31 (BBS5), and 20p12 (BBS6).

MKKS has sequence homology to the alpha subunit of a prokaryotic chaperonin in the thermosome Thermoplasma acidophilum.

Here we report the positional cloning and identification of mutations in BBS patients in a novel gene designated BBS4.

What was once thought to be a homogeneous autosomal recessive disorder is now known to map to at least six loci: 11q13 (BBS1), 16q21 (BBS2), 3p13 p12 (BBS3), 15q22.3 q23 (BBS4), 2q31 (BBS5) and 20p12 (BBS6).

Cases of BBS mapping ro BBS6 are caused by mutations in MKKS; mutations in this gene also cause McKusick-Kaufman syndrome (hydrometrocolpos, post-axial polydactyly and congenital heart defects).

|
In addition, we recently used positional cloning to identify the genes underlying BBS2 (ref. 16) and BBS4 (ref. 17).
|

|
The BBS6 protein has similarity to a Thermoplasma acidophilum chaperonin, whereas BBS2 and BBS4 have no significant similarity to chaperonins.

|
Here we report the identification of the gene BBS1 and show that a missense mutation of this gene is a frequent cause of BBS.

BBS is known to map to at least six loci: 11q13 (BBS1), 16q21 (BBS2), 3p13-p12 (BBS3), 15q22.3-q23 (BBS4), 2q31 (BBS5), and 20p12 (BBS6).

Although these loci were all mapped on the basis of an autosomal recessive mode of inheritance, it has recently been suggested-on the basis of mutation analysis of the identified BBS2, BBS4, and BBS6 genes-that BBS displays a complex mode of inheritance in which, in some families, three mutations at two loci are necessary to manifest the disease phenotype.

|
In the present study we evaluate the involvement of the BBS1 gene in a cohort of 129 probands with BBS and report 10 novel BBS1 mutations.

|
A mutation of the BBS1 gene on chromosome 11q13 is observed in 30%-40% of BBS cases.
|

|
In six cases, we identified a recessive mutation in a BBS gene (three in BBS2, two in BBS4, and one in BBS6).
|

|
No BBS1, BBS3, BBS5, BBS7, or BBS8 mutations were identified in our series.

These results suggest that the antenatal presentation of BBS may mimic Meckel syndrome.

|
To date, 16 BBS genes have been reported, seven of which (BBS1, 2, 4, 5, 7, 8, and 9) code for proteins that form a complex known as the BBSome.
|
17 |

|
Three additional BBS genes (BBS6, BBS10, and BBS12) have homology to type II chaperonins and interact with CCT/TRiC proteins and BBS7 to form a complex termed the BBS-chaperonin complex.
|
18 |

|
By characterizing BBSome assembly intermediates, we show that the BBS-chaperonin complex plays a role in BBS7 stability.
|
19 |

|
BBS7 interacts with BBS2 and becomes part of a BBS7-BBS2-BBS9 assembly intermediate referred to as the BBSome core complex because it forms the core of the BBSome.
|
20 |
22500027
|
BBS1, BBS5, BBS8, and finally BBS4 are added to the BBSome core to form the complete BBSome.
