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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.6).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0161 (2454/152352) while in subpopulation NFE AF= 0.0219 (1492/68028). AF 95% confidence interval is 0.021. There are 22 homozygotes in gnomad4. There are 1264 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 2454 AD gene.
