Genes affected

ADCY1 (HGNC:232): (adenylate cyclase 1) This gene encodes a member of the of adenylate cyclase gene family that is primarily expressed in the brain. This protein is regulated by calcium/calmodulin concentration and may be involved in brain development. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

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

The c.173A>G (p.Q58R) alteration is located in exon 1 (coding exon 1) of the ADCY1 gene. This alteration results from a A to G substitution at nucleotide position 173, causing the glutamine (Q) at amino acid position 58 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
