Genes affected

ADCY4 (HGNC:235): (adenylate cyclase 4) This gene encodes a member of the family of adenylate cyclases, which are membrane-associated enzymes that catalyze the formation of the secondary messenger cyclic adenosine monophosphate (cAMP). Mouse studies show that adenylate cyclase 4, along with adenylate cyclases 2 and 3, is expressed in olfactory cilia, suggesting that several different adenylate cyclases may couple to olfactory receptors and that there may be multiple receptor-mediated mechanisms for the generation of cAMP signals. Alternative splicing results in transcript variants. [provided by RefSeq, Nov 2010]

The c.2710G>A (p.E904K) alteration is located in exon 21 (coding exon 21) of the ADCY4 gene. This alteration results from a G to A substitution at nucleotide position 2710, causing the glutamic acid (E) at amino acid position 904 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
