Genes affected

ADCY8 (HGNC:239): (adenylate cyclase 8) Adenylate cyclase is a membrane bound enzyme that catalyses the formation of cyclic AMP from ATP. The enzymatic activity is under the control of several hormones, and different polypeptides participate in the transduction of the signal from the receptor to the catalytic moiety. Stimulatory or inhibitory receptors (Rs and Ri) interact with G proteins (Gs and Gi) that exhibit GTPase activity and they modulate the activity of the catalytic subunit of the adenylyl cyclase [provided by RefSeq, Jul 2008]

The c.3456G>C (p.E1152D) alteration is located in exon 18 (coding exon 18) of the ADCY8 gene. This alteration results from a G to C substitution at nucleotide position 3456, causing the glutamic acid (E) at amino acid position 1152 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
