MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a coiled-coil and calcium binding domain protein that appears to play a critical role in cilia formation. Mutations in this gene cause Meckel syndrome type 6, as well as Joubert syndrome type 9. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009]
PHENOTYPE: Mice homozygous for a null allele exhibit embryonic lethality with multiorgan defects related to cilia biogenesis. Homozygotes for a gene trap allele show randomized body axis, holoprosencephaly, and microphthalmia. Homozygotes for an ENU-induced allele show heterotaxia, congenital heart anomalies, kidney and eye defects, polydactyly, and cleft palate. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to G transition at base pair 44126696 in the Genbank genomic region NC_000071 (Build 37.1) for the Cc2d2a gene on Chromosome 5 (GTGAGTATTA ->GTGAGTGTTA). The mutation is located within intron 34, seven nucleotides from the previous exon 34 (from the ATG exon). The Cc2d2a transcript contains 40 total exons. Multiple transcripts of the Cc2d2a gene are displayed on Ensembl. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Cc2d2a gene encodes a 1633 amino acid protein that may be involved in cilia formation. CC2D2A contains a C2 domain at amino acids 1068-1180, which is a Ca2+-dependent membrane-targeting module found in many cellular proteins involved in signal transduction or membrane trafficking (Uniprot Q8CFW7).
