Genes affected

ADCY6 (HGNC:237): (adenylate cyclase 6) This gene encodes a member of the adenylyl cyclase family of proteins, which are required for the synthesis of cyclic AMP. All members of this family have an intracellular N-terminus, a tandem repeat of six transmembrane domains separated by a cytoplasmic loop, and a C-terminal cytoplasmic domain. The two cytoplasmic regions bind ATP and form the catalytic core of the protein. Adenylyl cyclases are important effectors of transmembrane signaling pathways and are regulated by the activity of G protein coupled receptor signaling. This protein belongs to a small subclass of adenylyl cyclase proteins that are functionally related and are inhibited by protein kinase A, calcium ions and nitric oxide. A mutation in this gene is associated with arthrogryposis multiplex congenita. [provided by RefSeq, May 2015]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PP2: Missense variant where missense usually causes diseases, ADCY6
• BP4: Computational evidence support a benign effect (MetaRNN=0.023034751).
• BP6: Variant 12-48771867-C-T is Benign according to our data. Variant chr12-48771867-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 3039504.Status of the report is criteria_provided_single_submitter, 1 stars.
