Genes affected

CHRM4 (HGNC:1953): (cholinergic receptor muscarinic 4) 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, mouse studies link its function to adenylyl cyclase inhibition. [provided by RefSeq, Jul 2008]

The c.524T>C (p.V175A) alteration is located in exon 1 (coding exon 1) of the CHRM4 gene. This alteration results from a T to C substitution at nucleotide position 524, causing the valine (V) at amino acid position 175 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
