Genes affected

ADCY2 (HGNC:233): (adenylate cyclase 2) 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). This enzyme is insensitive to Ca(2+)/calmodulin, and is stimulated by the G protein beta and gamma subunit complex. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Nov 12, 2021

The c.2077A>C (p.M693L) alteration is located in exon 16 (coding exon 16) of the ADCY2 gene. This alteration results from a A to C substitution at nucleotide position 2077, causing the methionine (M) at amino acid position 693 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
