Genes affected

CC2D2A (HGNC:29253): (coiled-coil and C2 domain containing 2A) 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]

The c.1041C>A (p.D347E) alteration is located in exon 12 (coding exon 10) of the CC2D2A gene. This alteration results from a C to A substitution at nucleotide position 1041, causing the aspartic acid (D) at amino acid position 347 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
