Genes

A number sign (#) is used with this entry because Bardet-Biedl syndrome-15 (BBS15) is caused by homozygous mutation in the WDPCP gene (613580) on chromosome 2p15. One such patient has been reported.

Description

BBS15 is a form of BBS caused by mutation in the WDPCP gene, a planar cell polarity gene (Kim et al., 2010).

For a general phenotypic description and a discussion of genetic heterogeneity of Bardet-Biedl syndrome, see BBS1 (209900).

Molecular Genetics

In a patient with a clinical diagnosis of BBS, Kim et al. (2010) identified a homozygous mutation in the WDPCP gene (613580.0001). Both parents and an unaffected sib were heterozygous for the mutation. Kim et al. (2010) also identified 2 heterozygous missense alleles of WDPCP in 2 individuals with BBS that were absent from 384 ethnically matched controls, HapMap, and 1000 Genomes. No clinical details were given for any of the patients.
