Genes affected
ADCY3 (HGNC:234): (adenylate cyclase 3) This gene encodes adenylyl cyclase 3 which is a membrane-associated enzyme and catalyzes the formation of the secondary messenger cyclic adenosine monophosphate (cAMP). This protein appears to be widely expressed in various human tissues and may be involved in a number of physiological and pathophysiological metabolic processes. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2016]
CENPO (HGNC:28152): (centromere protein O) This gene encodes a component of the interphase centromere complex. The encoded protein is localized to the centromere throughout the cell cycle and is required for bipolar spindle assembly, chromosome segregation and checkpoint signaling during mitosis. Alternatively spliced transcript variants encoding multiple protein isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]

ADCY3-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesAug 23, 2024The ADCY3 c.3332_3333delGG variant is predicted to result in a frameshift and premature protein termination (p.Gly1111Glufs*14). To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. This variant resides in the final exon of this gene, and it is unclear if the resulting mRNA would undergo nonsense-mediated decay. Frameshift variants in the last exon of ADCY3 have been identified in association with autosomal recessive severe obesity and have been associated with decreased catalytic activity in functional assays (Saeed et al. 2018. PubMed ID: 29311637). Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
