Genes affected

AVEN (HGNC:13509): (apoptosis and caspase activation inhibitor) Involved in negative regulation of apoptotic process. Located in membrane. [provided by Alliance of Genome Resources, Apr 2022]

CHRM5 (HGNC:1954): (cholinergic receptor muscarinic 5) The muscarinic cholinergic receptors belong to a larger family of G protein-coupled receptors. The functional diversity of these receptors is defined by the binding of acetylcholine and includes cellular responses such as adenylate cyclase inhibition, phosphoinositide degeneration, and potassium channel mediation. Muscarinic receptors influence many effects of acetylcholine in the central and peripheral nervous system. The clinical implications of this receptor are unknown; however, stimulation of this receptor is known to increase cyclic AMP levels. [provided by RefSeq, Jul 2008]

Jan 17, 2023

The c.163C>T (p.R55C) alteration is located in exon 1 (coding exon 1) of the AVEN gene. This alteration results from a C to T substitution at nucleotide position 163, causing the arginine (R) at amino acid position 55 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
