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 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.22119033).

The c.115T>C (p.C39R) alteration is located in exon 1 (coding exon 1) of the ADCY2 gene. This alteration results from a T to C substitution at nucleotide position 115, causing the cysteine (C) at amino acid position 39 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
